Help ? need some SO advice

Ashlee
So I thought my SO and I were on the same page. I stopped using birth control and just said whatever happens happens. Ever since I got my BFP he's said comments like "we aren't ready this could ruin our lives" and "we need to take care of this.. It's not time" or "baby's are so expensive we don't have the money". I am just sick over this. We are both 25 years old, he has an amazing job with good pay and benefits, I also have a stable job and am finishing part time nursing school to become and RN. Yes babies are expensive, and yes this can be stressful, but even if you are TTC no one is 100% ready for a baby. He thinks I won't finish my schooling once the baby is born and I have come way too far to let that happen. We have a wonderful support system and have a nice house. I am just so terrified that when I put my foot down and say I am doing this with or without him that he will want to end things all together ? Please tell me this is just a phase and he will get over it. This should be such a joyous time in our lives. Has anyone else had this happen?? I could really use some advice. Thanks everyone
