I've been with my dp for 4 years. He's always been a moody type from the beginning, even his mother warned me about it when I first met her. We were together about a year when we had a huge row. I already have 3 kids from my previous marriage, my dp understandably wanted a child but as I was nearing 40 I didn't feel it was right for me also I didn't know how stable our new relationship was. Anyway I was direct with him and he walked out. During the time we were apart, I got some counselling as my confidence was shook. I started to get more confidence and my self esteem came up. We were apart for only 2 months but then he contacted me saying he wanted to get back with me and that he was now sure he didn't want a child and that I was enough. I took him back. For the next 2 years he lived in a different city so we only saw each other at weekends and the relationship really went well. He asked me about a year ago to reconsider having a child for him. I agreed because I didnt want to lose him again. We tried naturally and miscarried, then did 2 courses of IVF which both failed. We found out then that his sperm is bad. We decided to go one last time for IVF as we now knew the cause why the embryoes kept arresting. Because of my age now 44, i agreed to using donated eggs. Around this time, he decided to go back to college. He moved in with my kids and I. Again I started to see his mood swings. He makes "jokes" about me not exercising (he likes to keep fit) also about how I clean, how I parent, what groceries I buy, he doesn't help much around the house but is quick to point out all my short comings. We had a family function recently and my aunt had words with him as she felt he spoke to me disrespectfully. I think I'm so immune to it, I was surprised at someone else's reaction. It has now made me rethink things. I do not want to go ahead with the IVF. I'm 45 next birthday and I want to raise the 3 I already have the best I can instead of adding another child to the mix. We only have s☆x every now and again as he's always too tired. I feel like he's not attracted to me but he denies this. I'm paying for everything while he goes to college including the IVF. I just want him to be nice to me, to feel loved but I don't. If I bring any of this up, he goes off the deep end and will convince me I'm in the wrong. I will bring the IVF up in a few days as he's in a mood the past few days and I know it will escalate, I also know he will leave. My fear is he is using me for a) a baby and b) to get thru college. What do you think AIBU?
