Search Results: after the girl has cheated

So yesterday my boyfriend told me he went to breakfast with his friend and his friend’s girlfriend and he told me later he was gonna spend the night with him. Which I automatically did not believe. Because I find it weird that after so many months of him and his friend not speaking and him not hanging out with him that he randomly decided he wanted to have breakfast with him. Also we are all in our 20’s why do you feel the need to spend the night at another grown man’s house with his girlfriend? That’s weird to me. Anyways I told my boyfriend I didn’t care if he spent the night as long as he showed me proof he was there. I said this because he has a history of cheating on me with some girl he barely knew and he ended up getting he pregnant (which is another long story).. and I decided I would stay because I love this man so much and we been together for so long and I thought we could move past this together. At the time he was really remorseful and I felt like that was really just a mistake (big red flag). His whole family wanted me to stay.. I grew a bond with everybody. Back to my original story, he didn’t show me any proof. He said he didn’t care enough to go to his friends house if we were gonna be going back & forth. Fast forward to 3 this morning, I wanted to look at his phone to see if he actually made plans with his friend and I didn’t find any messages between him and his friend or any phone calls... weird right?
