I want to leave my husband…

My husband and I have been together for 7 years, married for 3 and we have a 1 year old daughter together. Up until having our daughter, our relationship was very toxic, we fought 24/7, he said a lot of hurtful things, I yelled a lot and he drank a lot. We both were just to afraid to make the plunge and leave.

Once we had our daughter, things changed but I also changed. I’m no longer interested in him, my main focuses are my daughter and my career. I now am fully able to support her and myself if needed. I was always so dependent on him before then. After having her I feel like I gained so much inner strength.

The sad part is he’s actually changed also. He tries a bit more with our marriage and he’s an amazing amazing father. I cannot say enough good things.

But physically and emotionally and socially speaking I’m not attracted to him anymore. I don’t want to have sex with him, I don’t want to hang out with him. We don’t have the same interests. I don’t know if it’s a new parent thing or I’m genuinely done with him. I need some advice because I seriously want to ask for a separation, I cannot live in a marriage that I am unhappy but I also feel so much guilt.

Also to edit: if I left, clearly we’d share custody and there would be no pettiness there. I’d hate to not have her full time but my happiness is being affected by faking the happy family act.
