ADVICE PLEASE LADIES

I think this is going to be a long one so I’m sorry, I don’t really know where to start but I’ve been with my boyfriend a few years now and things were full on from the start but we live together we just moved into a new house a 2 bed one room is a nursery, we’re engaged we were even trying for a baby and got our bfp but I miscarried at 8 weeks 😢 also I’m very very close with his family, so it all sounds perfect and I know this makes me a horrible person but for a while I just don’t feel in love anymore, I don’t even really enjoy his company anymore like part of me still feels like I love him as in I really care about him I never want to hurt him ever but I just don’t know what to do I feel like I can’t just leave we’re supposed to get married and I know if I don’t love him anymore I should just leave but it doesn’t feel that easy it’s scary and I’m scared to hurt him and what his family will think, I know that’s probably what you guys will say as well I know it’s not fair on him either but I can’t how do I do this not in a horrible way, I spoke to him the other day saying I don’t really feel happy in our relationship anymore and he just cried loads and said please don’t leave 😭 I don’t want to hurt him
