Heart Broken

I don't know how long this will be, that being said... I need some real advice. I'm not some school girl who lots her emotions rule her actions. I am a wife and mother. I have responsibilities. But here's the thing; My husband and I have been talking about having more than one child for a while now, and every time I talk to him, let him know that things need to happen when I'm in my fertile week he gets an attitude. I've spoken to him so many times about how I feel and asked him if he really wants more kids, and he never gives me a straight answer. It's always, "If I didn't want anymore, I'd tell you."

I don't know what to do. I have PCOS. For those of you who don't know what that means, it means I can't get pregnant very easily, let alone on my own. I don't ovulate normally so I need help and I have less of a chance of getting pregnant every month vs someone who doesn't have it. Last month I took ovulation tests all month up until I had my period. No luck. I didn't ovulate. So, after my period ended, I started testing again. Today, I think I got my positive. I let him know, and all he did was get angry with me.

It broke my heart. I cried while he slept. I don't understand why he gives me hope if he's not even willing to try to have another child. I want another child so much. I want to have a normal family. But... we're not normal. He's older and has so many health issues. I do my best to accommodate him and do my best to support him. He has a bad back... a disk slips and he can't get an erection. I understand all this. But he won't even try. And when I asked why he wont try, more arguing. Then he has the audacity to tell me if I want a baby so bad, find another man to get me pregnant. I don't think I've ever been more angry or hurt in my life.

What should I do? How am I suppose to make sense of this?

Please, any help or advice is appreciated.
