Starting again

I’ve been in long term relationships for the last 10 years, the first one lasted 4 and the next one with my current husband lasted 6 years when we got married. 7 months into marriage and I’m thinking divorce due to irreconcilable differences. But I don’t remember the last time I was alone and it scares the hell out of me just to imagine starting things all over again and dating strangers and trying to figure out if they are a good match or not. All of this is giving me major anxiety just thinking about getting out of the comfort zone my husband has created for over these last 7 years.
