So my girlfriend ( sons mother ) and I went out separate ways while that happened before I had moved out she was seeing another guy or saying she wasn’t but was with him every weekend and every chance she got so I had moved out and started to do anything I could for my son... we got back together about two months later and she had openly said she slept with this guy because I accused her of doing it so she did once I had moved back in I noticed her always hiding her phone and then seen he always liked her Facebook post she recently told me she didn’t stop talking to him because I had my highschool gf in my Facebook witch is happy with her own two kids and a family and has now told me she don’t know if she has feelings for another man ( the same guy ) as much as I love my son and so Everything for him am I wrong for leaving and standing up for what I thinks right
