So first off, Instagram has caused a lot of problems in our relationship and it was his idea to delete it. When we get in an argument, he downloads it and follows a bunch of girls. Remember this for later. Well about 6 nights ago he didn’t get home until 2 am. He had said he was gonna go fishing, but he left the house at 5 pm, so I was like okay he’s gonna go fishing with some buddies. I later our find out this girl was there and it’s his cousins adopted sister. He says he doesn’t see her as his cousin though and idk how someone can fish at the lake for 9 hours. So he gets home and I asked him it. And I was like is there something you’re not telling me? Do you feel some type of way towards her? He then bent me over the couch and dry humped me saying yeah I totally wanted to bend her over and fuck her like this. I pushed him away and was like are f***ing serious and then he put his hand down by his crotch acting like he was bobbing a girls head up and down and said yeah I wish she was here to suck my dick. I threw his clothes in the living room and told him he was sleeping in there. I later see that he downloaded Instagram, blocked me and followed a bunch of girls including this one. 2 nights ago he didn’t get home until 8 am and said he had been playing beer pong. Once again, she was there. Last night he came in the room saying he wanted to be a family and that he was sorry that he would unfollow all those girls and may even delete it again. I’m still blocked and find out he is still following that one girl. I asked him about it and he made a big deal and was like it’s just one girl. I asked him why he kept following her when he had unfollowed the others considering she has already cause problems in the relationship. He blew up and couldn’t answer it. I feel like I should be worried about him and her after everything that’s happened. What do y’all think?
