Broken 💔💔💔💔

My fiance and I broke up over a week ago but he wants to be F*ck buddies and we are still living together. I still want to get pregnant but I'm not trying to do it to win him back. I'm still in love with him, more than ever. We fought a lot since we lost our son and it's just been so hard lately. I still wake up next to him every morning and I just want us to be back together and happy like we used to be. We had our issues but he is the only man that really understood me. I started all of the fights with petty nonsense that just wasn't worth it. I'm struggling so hard right now on what to do. My 2 year old little girl sees this man as her father and I don't want to hurt her too. Please help me. I'm losing my mind right now. I can't even look at my rings because they hurt so much.
