Hey all, not sure if I am posting this in the right thread but my question is how do you get over the irrational worry of losing your girlfriend and not finding someone easily after?

This is not my first girlfriend and I have been somewhat successful with women in recent years but this is something I am noticing within myself with my current gf.

I am in great shape and financially stable but this is the one area in my life that you can say I am a bit insecure about.

Thank you
