Search Results: dating two people at once

My boyfriend and I have been dating for 6 months. We started talking 5 months before that. [(He broke up with me after a month because I wouldn't sleep with him. But we got back together.)((I waited for marriage with my exhusband and I view sex differently than others do. He was very abusive that is why we are no longer together.))] Anyway, he broke up with me again in November saying that he couldn't deal with me having a child.

He slept with a couple people (including a pretty ex) texting more. We got back together after about three weeks of us being broken up even though we were around each other all the time.
I got let go and I saw that he texted a girl from work the day after I got fired. I confronted him about it. He said he didn't know why he texted her that it seemed like something to do because he had to ask about his schedule. But that it wouldn't have went anywhere. I asked if he wanted an open relationship but he said no because he wouldn't want me doing the same. I've seen him texting and talking to two other ones.
I asked him what he was doing. If he really wanted a relationship with someone else or what. He said it was just talking and running into each other at work. Said I was who he loved and what he wanted. That it was just conversation that he did it for excitement.
I asked him if I wanted him to join a dating app if he would for me. He asked why? I told him if it was just conversation and flirting. He could do that. He said he deleted stuff like that a long time ago and that he didn't need them. So I asked if "the endgame really was to sleep with her." (Because that to me sounds like he actually likes this person and really wants to persue her.) He told me the endgame was to be 89 sleeping with me.
But I asked him once more before work if he actually wanted to have sex with her. If it went that far if he would not. He said "What do you want me to say?" Then he replied "Yes. I would fuck her. And then I'd leave her alone. And she'd leave me alone."
