I feel like my bf doesn't love me no more.

we have a 1 year old girl and another baby on the way. we are suppose to move into a his parents new house. when we got the news (yesterday) that they wanted us to live there instead of them we were all in shock. they worked hard to buy that house and fix it up. we live with them currently in their other home and the plan was to stay here when they moved which was also awesome because we were just going to pay 800$ rent and a bill. my bf kept telling them it didn't feel right but his mom wanted it this way. when everything was said and done my bf didn't seem happy. I asked what was wrong and he said nothing. I kept nagging him because it was bothering me. he did not seem happy like at all. he finally said that he just thinks we're going to be hurting financially for maybe a month or two. I told him I can start working and he said no that he was necessary that he just wished we had another month or so to save up more money. after that it still seemed like something was wrong. I asked if he was excited and he shrug and said yeah I guess idk. it broke my heart because he wasn't opening up except just kept saying that the next month's will be hard. he is never negative about anything and usually goes along with anything as time passes so it was weird to see him like this. I sat him down and asked him if he felt stressed and he said no. I asked him if he still loves me and he said yes. so why am I getting these weird vibes from him? I checked his phone today and I didn't see anything. I know i shouldn't have but I feel like he should be happy or excited to move out together. I have never had a place to myself and I feel like I'm sharing this excitement to myself. he also doesn't talk much to me after or before work. I feel like a toddler followjng him around making up conversations but he is always quite playing games or he goes outside a while to smoke weed. after work he goes and smokes with his friends and it never bothers me because he doesny take long at all but when it comes down to me I feel alone.. any help Pls??
