Conflicted

Please no judgement. I’m looking for honest opinions but be gentle. Not everyone has thick skin... So I am currently going through a divorce. It started about 8 months ago for multiple reasons it just wasn’t going well and there was a lot of things that needed to change... anyway. We separated( haven’t filled out the paperwork yet) he moved out, we do every other week with our child. About 4 months into our separation I met someone who made me feel butterflies, Sweaty palms, and just all around like good nervous if that makes sense. Anyway, I made it pretty clear that I wasn’t looking for anything serious and if you are anything like me.. that’s hard. I have a huge heart and care for people so deeply. Even if I just met them.. so fast forward... we’ve been dating now for about 3ish months... well my soon to be ex husband started to clean up his act and started reaching out... I miss him dearly but usually when he changes something, it lasts for about a week or so and then goes back.. I have been very open with both my current relationship and my soon to be ex on how I am feeling but I am so conflicted.. this new guy has been so wonderful. He calms my anxiety and makes me feel so alive when I am with him. Even if we are being couch potatoes... but my husband is someone I decided to be with for the rest of my life at one point in time.. and I’m not sure if these feelings are because I still truly romantically love him or just because we share the one good thing in our life... our kid... has anyone ever been through a similar situation and is willing to give insight? I know every situation and person is different. Just looking for some type of guidance.. 😔
