Preface I am 29 and my GF at the time was 22, we have two kids under 2 and lived in a nice condo, I was the sole bread winner, she cooked, cleaned, took care of kids.

Around April my dad who is a drug addict got kicked out of his place, I let him move in temporarily my GF was vehemently opposed to this, and started bringing it up constantly how we needed a plan to get rid of him, he really wasn't bad at all, and treated her fine.

During this time she started going to her moms house 2 - 4 hours a night, suddenly brought up going back to school, and as May hit told me she no longer wanted to have sex with me for fear of getting pregnant. ( She put up a new Facebook photo of herself looking pretty at this wedding)

Fast forward I kicked her out of our place, we were NC for a month and when I seen her she told me she had got on birth control, claims now she had made the appointment before she had even left here (news to me), whenever I see her she seems genuinely unhappy to see me, and plays text games, such as not responding for hours, or claiming not to get texts, or other times being hyper emotional with words, we've hung out several times and I did have sex with her and probably gave her the best fucking since I've known her for the past three years.

She claims she wants a house and to be together, but when I go forward with those plans, she pulls back, and while with her something just feels wrong,

What exactly happened here?
