Falling out of love

Me and my husband have been threw hell and back kids from other people a child of are own and we have made it threw. These past few weeks idk I don’t wanna have sex with him I don’t touch him like I used to just don’t feel the same idk but he doesn’t give much effort either could it be there were falling out of love. Like when it comes to us two I just don’t see it but when it involves are children it’s just hard to make a decision we haven’t spoke in 3 days and we’re not fighting we just don’t have anything to talk about I ask him what time he work if I’m picking kids up things like that but conversation between husband and wife that we used to have is a fading memory we’re going on 4 years married 9 years together. I’ve had so much on my mind and just depressed I had surgery last week polyp a cyst removal on my uterus trying to conceive but know I’m second guess if getting pregnant is even what I want anymore and that’s all I’ve wantted for 1.5 years now I crashed the car last week and it’s just one thing after another I think we’re finally at a point we might be truly drifting apart. We had sex after doc appt cleared me and it was my first time ever not wanting to have sex with him I was hoping my doctors told me another week idk what I’m feeling cause it’s so new but this is early going to make us or break us and I’m just not sure my next step he doesn’t even know how I feel because he can’t open his eyes and see there is something wrong but at the same time I know he feels it too
