Counseling

Starting marriage counseling this month because my husband blindsided me this weekend saying this isn't working and he wants a divorce. We have 2 kids, 4 and under 1. We have been struggling a little bit for a long time now, a lot due to infertility and loss and some due to ineffective communication, and havent been able to fix it on our own. Ive been in therapy for about 2 years and he continually refused individual therapy until yesterday. I'm Catholic and was raised not believing in divorce. He was raised in a dysfunctional home. I had a complete meltdown that first night. I've been VERY in my head about it. Today I had a moment of clarity that I am a GREAT mom. I work from home and have had our kids home with me for the last 2+ years as well. My husband has been withdrawing from our family over the last year especially, working a lot on top of his normal expectations and finding things to do outside of our home. I do the cooking most nights. I do 80% of the cleaning. I handle the laundry and the schedule and everything family organization wise. If we do end up separated or divorced...I will be okay, and so will our kids with me as their mom. I will be able to have more kids if I still want to, and even get a dog if I want. The only thing I wouldnt be able to do is move away from our current city, which I really hate living in. But I will be okay. Does anyone have any advice on counseling? Insight? Stories of hope for us?
