My boyfriend still goes around his ex girlfriend and at first he claimed it was just to see and be around his daughter (who isn’t really his daughter, it’s his exes daughter and she became like his step daughter when he was still dating her) He doesn’t know but I have been on his ex’s Facebook page just to see if that was the only reason he goes around her and it proved that that isn’t why. A few times, late at night, when he has stopped answering my calls and texts, she has posted videos with him on her Facebook story and Snapchat. I even saw that the three of them even went out for breakfast for her daughters birthday a few days ago and also from her Facebook story today I saw he went to her birthday party but he lied to me and said he just had been busy and then stopped answering calls and texts as usual. She also obviously feels secure and comfortable enough to post him. I haven’t said anything because of how I found out.
