Hello everyone. New here and looking for advice.
I have been with my GF for 9 years (we met in high school) Im 25 and shes 23, we have a son together and hes great, I love my boy so much. But my GF and I have recently moved out of our household and moved to different places (about two months ago) with the intention of moving back into a place after we get some time away from one another. I'm in a smaller apartment now and shes living with her sister. I get the munchkin on Friday till Sunday night. The reason for the move is because she was seeing another guy and she admitted that they were flirty and what not but it never got sexual even though she was out late with him a few times, that's what she says, it sounds like the truth but you never know. And to be honest I forgive her for being interested in another guy and whatever. But our relationship has honestly been very poor for the past two years or so, we are very rarely intimate, like once a month rare. We don't do much together now, shes always up and ready to go hang out with her family and friends but I got to twist her arm to get her to spend time with me. She rarely takes my opinion into consideration, for example she got two decent sized tattoos on her arm and she didn't even talk to me about it, She just said "I didn't think I had to ask you". If I was just a friend I could understand not talking to me but we have been together for 9 years and have a son together. In my opinion that's kind of messed up. I feel like shes bored with the relationship and the only reason she has not left is because of our son.
There is much more to add but i don't want to sounds like a cry baby teen. But my question is what should I do. I love my son and I love my GF but I don't want to be in a relationship if she doesn't want to be in it. What should I do and how should I approach it, that is if anything should be done?
