Buying a home (Little bit of a long Vent)

Short back story; my SO was with his ex for 9 years. In that time, they bought a home together, which in turn upon the end of their relationship, went back to the bank as they filed bankruptcy.

Fast forward to our relationship; 5 years, two kids (the eldest is a daughter I share with my ex husband), our two year old son, and expecting our second boy (final kiddo) in December. We live in an older manufactured home that starting in the summer became of interest to mice. We live out in an area where it is to be expected, and the work that needs doing on this house makes us even more susceptible. Needless to say, we've been hunting down a new residence for sometime now. I'm through with renting, and we were approved for a loan about a month and a half ago. We've been looking at many houses, some which I feel could be manageable with a few changes here and there, but he's been a lot more difficult to being open minded than I am.

The last home he bought, he HATED, and only did so because he wanted to be accommodating and I don't want him cornered into that again. I really want him to be driven and love the home we purchase together. However, as time marches closer to my due date and we still haven't landed a new home, I'm terrified of being stuck in the super small quarters we're in now. I don't want to bring our new baby here 😭 I'm a big believer that what's meant to be will be when it's meant to, but I'm still irritated and worried. Anyone else been in similar shoes and have any words of encouragement?
