Need advice ๐Ÿ˜”

My boyfriend and I just had our first child on October 10th. Unfortunately she got an unexpected illness at 10 days old and passed away. I have been hurting so bad but Iโ€™m to the point where I feel that I need another baby. Not to replace her but to give all this love I have built up. Iโ€™m so desperate for a baby, Iโ€™m sure many of you know the feeling. I just found my boyfriend talking inappropriately to other women. It breaks my heart because now Iโ€™m not sure if I should leave him or not and if I do, I cannot get the baby that I need so badly. It sounds crazy but I wouldnโ€™t even care if he got me pregnant and then we broke up. Thatโ€™s how bad this is. Or should I keep trying with him because he didnโ€™t physically cheat as far as I know. Any thoughts?
