Tl;Dr boyfriend forced us to open relationship, but now he’s feeling insecure and jealous of the people I meet. Best way to help him handle these feelings while being fair to myself?

My boyfriend and I opened our relationship over a month ago, by his demand. Literally told me we open it or he’s just going to break up with me. He made up a bunch of reasons but now it’s obvious he just wanted to be able to sleep around again. I wasn’t a fan of the idea, but I agreed and honestly I really am enjoying it. But now he seems like he isn’t.

We had an open relationship at one point when we very first got together, and he was sleeping around A LOT and I wasn’t because I believe I’m some level monogamous because I couldn’t be with anyone else because it felt wrong, I was in love with him. This has changed, this time I’m actually going out with other people and it’s been really nice.

He has not had much luck, he’s only met a couple people and both haven’t been the best. I’ve met quite a few people and it’s been amazing, I’ve had people taking me out for diners and getting me gifts (stuff my boyfriend has never done for me btw) as well as just really exciting experiences it’s some amazing people.

My boyfriend and I agreed for opening the relationship we would have VERY open dialogue about everyone we meet, and he’s been getting pretty upset hearing my experiences. I’ve asked if he wants me to stop telling him or to close the relationship again but he says no. I now limit the details I tell him (which he doesn’t do for me, he gives very intense sexual details to me that I don’t care for… lol.)

He’s gotten really insecure the last week and tells me several times a day he’s lost his confidence and doesn’t like himself and stuff like that. I’m trying to be there for him, but it’s frustrating that he’s likely only because I had the audacity to have a good time. Like he expected that when he opened the relationship only he would be able to have fun.

I don’t think he will close the relationship because he’s still trying really hard to meet people, but I can tell he doesn’t like me being with other people and I feel like soon he’s gonna start shutting down any good connections I make. He’s already asked me to stop seeing one person and only gave the reason “I just have a bad feeling about it”

How do I take in to consideration all these ways he’s feeling about things, while being fair to both of us? I don’t want him feeling insecure in our relationship, but I’m just doing exactly what he wanted us to do.
