Apologies for the long post but looking for advice.
Watching tv laid on DP the other day I saw he had an odd app as he was scrolling though his phone. Took a chance to look at his phone last night to see he had said app (a friend ex H had used the same site to meet and message other women so this is how I was aware what it was) I clicked but everything was deleted. I took down his username and last night signed up and messaged him. He messaged all last night saying about meeting in person and telling me what he wanted to do to me etc. slightly encouraged by me but I just wanted to see what he was doing on there. He's messaged again today while I've been sat in the next room. I would normally trust him, been together 5 years and haven't had suspicions before.
No kids together but we both have kids, we are very intertwined in each others lives. He moved to my house when a change in circumstances meant I could no longer afford it alone and that still stands. I literally cannot afford the rent and bills etc on my own.
Most adult relationships I've been in I have been cheated on, part of me thinks do I stay for a comfortable life, we get on fine the kids are all happy and I'm generally happy. It just depends if I can move past this.
I would be open to an open relationship so get the best of both worlds if that's what he is lacking. The last year and a half have been awful - I lost a baby at the end of 2023, a lot of mixed feelings and he rushed into a vasectomy. Since then sexually he hasn't been as active as we were before or wanting it as much, I let myself go and put on a couple of stone (although have lost nearly half now again I'm better mentally) I feel like my sex drive is back but his has slowed down. We are still sexually active but it's only really if I initiate. If we were open I would explore also and something I have thought about previously.
Part of me feels like LTB I deserve better, I know there are decent guys out there that won't cheat but I don't know if I will find that. It would also be impossible for me to date as the kids dad has basically gone awol the last year and barely has them. Another reason why I feel stability for the kids with this guy is needed.
I don't know what my next moves should be.
