Being immature and playing mind games
would be My guess. Some people never
Growup.

I stay away from things My ex might attend. I
have been no contact For 15 months. Its doable
if you take measures Which i did for my sanity
And healing. HUGS

There are only two real possibilities here for a reason. 1) he just wasn't thinking about it or two 2) he wants to rub it in that he has someone. If he wants to rub it in, then it means you still mean something to him and its his way of trying to induce pain for the sake of you ending it. That is my guess.

Does sound like he's playing games. Since you say you have "the same season tickets for seating each year," it seems pretty unlikely that it would be a coincidence that he ended up right in front of you.
As far as his motives, we can only speculate, but probably something along the lines of wanting to hurt you or wanting to make you feel jealous. Probably due to the fact that you cut off contact w him, he made a huge effort to make sure you'd see him. Either way, it's attention seeking behavior. It's hurtful, and I am so sorry you had to endure this. I had an ex-boyfriend that broke up with me, then showed up everywhere I went with my friends for seemingly months. We would just ignore him and move on elsewhere. I never found out WHY he did it (I maintained no-contact and he didn't approach us, he'd just sit and stare at us), but eventually it stopped.
Hopefully he will get tired of it once he sees it doesnt affect you. Honestly, hopefully he can't afford to keep going and you won't have to experience it again.
((((HUGS))))

Whatever you do dont post your stuff on
Social media. He could possibly be watching
You too. HUGS

I have to agree with what everybody else has said. The only constructive thing I can add is for future events, you might try changing your plans up....either different seats or night etc, just to cut him off at the pass as it were.

I think it's possible that he cares for you but I don't think he is romantically in-love with you as he is with his new girlfriend. There could be a number of reasons that he purchased tickets to a sporting event that he knows you attend. Generally speaking, guys don't tend to read as deeply into things like we do. Maybe his new found love enjoys the sporting event too. Perhaps he wasn't bothered at the possibility that he might actually run into you there because he knows that you enjoy that sporting event. Maybe doesn't care about that as much as you would care about running into him. Why? Because from my perspective and opinion if he truly loves you he would make some kind of contact with you. Maybe he would have hinted that might be there or called etc....The simply fact that he showed up to the sporting event with his new girlfriend, all the while knowing that you might be there tells me he has probably moved on romantically from you. No worries for you though! If possible try not to contact him at all and focus on your-self and moving forward. That way, eventually, someday you may meet a man who's on the same page as you AND who means what he says and says what he means. Love is more than words. Love is action.

One thing I will never do is change my season tickets just because he is playing mind games! These tickets have been in my family for many years now.

Sorry to hear you're hurting! Breakups are hard, and feelings can be fuzzy a long time after. Have you told some of your friends or your parents how you're feeling? It's important to build yourself a new support network.

Above all, please remember others' opinion and actions don't define your value. It's hard right now, but you're worth so much and there are guys out there who will treat you with the awesomeness you deserve. There are a lot of resources, so message me if you want to chat! You're in my thoughts and prayers!

Don't change your seats! Those are YOUR seats. He's just being an asshole playing mind games. It's actually pretty pathetic and manipulative. And I wonder how his new gf would feel if she knew he'd taken her to a game just to make you jealous. Dick.

@3cutiesmama. That's what I'm wondering too - Do you think he even told her who I was and what he was doing?

No, I don't think he told her. If he did, she would have been staring at you, or being overly affectionate or something. I don't think you should even acknowledge that you knew he was there. And if it comes up, I'd just say "oh really? I never even saw you!" He's clearly looking for a reaction from you. Don't let him have it!

@3cutiesmama - I didn't even think about what you just brought to mind - that if he would have told her who I was that she would have been staring at me, or being overly affectionate or something. I did make the observation though and told one of my friends that it was very weird to me that she did try and put her arm around the back of his seat a couple of times, and he would just lean forward in his seat like he didn't want her to touch him. And, I noticed a few times that she was either trying to hold his hand or rest her hand on his upper thigh and knee area and he wouldn't reciprocate her affection or touches. I thought that was VERY odd behavior, as when we were together as a couple and out in public, he was always initiating and showing me public displays of affection

^ Linda, who knows the dynamic of their relationship, but your reply above makes me feel like she is used to him generally being affectionate. And that when he wasn't, she was trying to initiate it, and as he didn't reciprocate she tried something else, etc. As though, he didn't want you to think they were together. Now obviously, that may not be. But that's my first instinct of the situation.
