I’ll be a single mother for the rest of my life

This is what my soon to be ex husband said to me when I filed for divorce. It’s been a little over a year and I it feels really lonely. I guess I felt more lonely when I was with him but I just wish I had someone who truly loved me and cared for me. Why do I expect this person to just show up on my doorstep? how do I even start dating again? I hate going out and meet new people I guess he was right. I’ll die alone
