My now ex and I have a 4 month old daughter, and for the past 3 weeks I haven' lived there because she kicked me out, I quit smoking weed, looking for a new job and a place to live. In the midst of trying to show her I am changing she has decided to invite over a married man and they got drunk and hung out in the hot tub alone and she had a hickey the next day when I came to see my daughter but she tried to say "it was a zit", on top of all of this she knows I'm not looking for another relationship not even talking to anyone else, and she has decided instead of working with me on our issues she has joined a dating website and has been flirting with other men, while refusing to even talk to me on a friendly basis, it' super hard because I love this girl more then I have loved before and she knows all of this, but doesn't try and talk with me and would rather flirt with strangers, it has me dying on the inside and she knows it. I have talked to her sister and told her all these things and agreed her sister was acting extremely shady about everything and agrees something isn' right. I' not sure what kind of advice I'm looking for but my friend told me I should join a group to see whay everyone says, he thinks I should drop her like a bad habit but that is the issue, my heart is on my sleeve for this woman.
