I'm 41 and I have a 3.5 year old daughter and a partner of almost 7 years. I've always wanted two children. Before I met my partner I was seriously considering single parenthood by choice. After we got together I was clear with him that I couldn't keep the relationship going if he didn't plan to have a family one day, he stuck with me. Our relationship has been pretty hard since becoming parents, I want a deeper emotional connection than he seems able to give and his work often takes priority over our family. When we argue he often says it wasn't the right time in his life to have a child. We recently spent 5 months trying for a second child, after which I had a very early stage miscarriage which was emotionally and physically very hard on me. My partner is now not able to give me a straight answer on if we can try again for a baby. I suspect he won't ever be able to give me the emotional or logistical support I want from a relationship. I'm doing well financially and don't need him to be here to keep up with the mortgage. I keep on thinking about asking him to leave and trying to have a second baby with donor sperm. It seems call callous to break up and then go straight into fertility treatment as a solo parent, but I'm 41, so time is really against me if I am going to ever have another baby. My daughter loves babies, and I really think she would be happy if she had a sibling, and I also think I'd provide a loving home and feel at peace if I could have a second child. I've tried and tried to mend the issues in my relationship with my partner. I'm heartbroken because I loved him so much when we were first together. I feel like we have made a lot of progress from our lowest point, but we often return to him being silent with me, me being frustrated with him. What's the right thing to do?
