Somethings off.

So I’m pregnant. I have a 5 year old kid and she’s great. I’ve been w/ my boyfriend since our sophomore year in high school. Going on 9 years next month. I recently found out that I’m pregnant and we had been trying for only 4 months. Now that it’s happening, he’s almost distant about it. He feels like it’s going to be weird w/ another baby. I understand that it will be different with it only being is 3 for almost 6 years but I don’t want a small family. I’ve made it a point in saying that and he seemed to be on board at the time. I just think that now it’s real and he’s unsure And I just think that if he felt like that he should have said something sooner. Now I feel like I’m carrying a burden. I don’t know if its the hormones or not but it sucks.

Any thoughts?
