I think my marriage is over..

We have been together almost 17 years and married 6. (Met at 16 years old.) My husband and I have been fighting constantly. There are so many problems we have but I feel they can be fixed. Mostly on my part. The breaking point is now he just feels we have no more connection. We have a 3 year old junior together and have always planned to have so many more ! I am so SO sad of thinking this is all over. Our son won’t have the siblings we’ve always hoped to have. (We Both come from families with our siblings so far in age from us. And hoped to have 5/6 children close in age to have each other as friends.) I don’t know why I’m posting here other than to get it out. I have nobody I can talk to. I don’t think there’s a way to salvage this any longer if he’s straight up saying we have no more connection. I’m just exhausted and feel defeated. 😩
