I was seeing this guy for nearly 4 months. We went on a family trip (me, him, and his two kids) to Disneyworld. We drove 22 hours (in my car) to get there. 3 days into our trip, my sister and brother called me to tell me that our mom, who was in the hospital, and taken a turn for the worse and wasn't given much time. (Before I left, she was ok, and my sister said to go ahead on the trip). I didn't want to disappoint the kids becaused I loved them.

So when I got the call, I booked a flight home. He and the kids would stay behind and finish the vacation, and drive my car back. He promised me (as well as his daughter, who was very upset that I was leaving) that I would stay with them for a week once they got home so that I wouldn't be alone.

When they finally got back (on his drive home he also decided to race my car...he said he was going 180km/hr), he "forgot" about his promise, and said "when I drink, I tend to exaggerate".

The day I arrived back home, I took a cab straight to the hospital. My coworkers and friends were texting, asking what was going on, am I ok? I texted him that I was rushing to the hospital because my mom was given only a few hours to live, and I was afraid that I wouldn't make it on time. His response? "What's your password to your Disney app?". Like he completely wasn't responding to what I was saying. I had to repeat it a couple more times, with no real response. By then I was thinking, wtf?

So fast forward 4 days later. He told me that he didn't mean what he said about me staying there. He asked why did I have expectations of him? I told him he promised, that's why I had expectations. He actually said "you are acting like your mom died yesterday." No, just four days ago...I should be over it by now.

So we fought, and he told me I was aggressive...that it was unacceptable. I went to pick up my car, and he put all the toys I gave the kids in the car. 

So wtf? Is he a sociopath? He seems to genuinely love his kids.

And I realized that he was always drinking in order to act "happy and normal". I never noticed at the time because he never appeared "drunk". But when he didn't drink, he was cold.

Even the night before I left Florida, we went for a walk, but not before we went to the liquor store so that he could buy vodka (in order to behave appropriately maybe?).

Over the 3-4 months, he told me he was mildly bipolar, has OCD...but I don't know what to believe anymore...his stories keep changing.

So what do  you make of this. I know that I should just let it go...move on, find someone who makes me happy. But it bothers me. How can someone (who seems to love his kids so much), be so inhuman?
