10 years of marriage

My husband and I have been married for over 10 years. He had demanding jobs for the last 4 years. Anyways he says we are growing apart and we don’t have chemistry. He wants to make it work but I’m worried that even if we do I’ll end up with a broken heart. We have a daughter who is 3 and another daughter on the way. I feel defeated and don’t know how I can raise my girls if it comes down to this. I feel scared to lose him. I have loced him all my life, I’m so scared to take the risk of trying and going to counseling. I worry I’ll get invested and end up alone anyways. We are planing to do more date nights and counseling. Has anyone been through this
