What if being with an unbeliever is my only chance of not being single?

I’m scared I’m going to be single all my life. All Christian men I know seem to be partnered up. I also don’t know if God even wants me to ever be married (I feel like he doesn’t). I want to be back with my ex who was an unbeliever but maybe God can change him? Also no man has ever pursued me in person, only online
