Long post sorry.. Want to adopt but husband says no..

So my husband and I have been trying to get pregnant for 6 years now.. we’ve been tested for literally everything and there’s no reason we shouldn’t be able to get pregnant.. He said a few months ago that if I’m not pregnant by his next birthday, which is in January, then he wants to start the process for adoption. I agreed and was very excited! I’ve planned on adopting even if I had my own children.. I grew up in foster care so it’s personal to me. But he’s now telling me that he doesn’t want to adopt, he doesn’t want to raise other people’s children, and that if we don’t eventually have a child then oh well. He said if I want a child then I’ll have to leave him because he’s not adopting. I’m seriously so heart broken and don’t know what to think.. or do. 😞 I want children sooo badly but I’m clearly not going to get that with him. I tried going the foster to adopt route to see if it would change his mind, with the whole cost and everything etc. Told him we could continue to try for our own at the same time. He still said no way, he’s not raising kids that aren’t his. I’m just so devastated ☹️ I don’t know what I’ll get out of posting this I just need to vent.
