Um, yes?

Romantic relationships are often not the strongest ones and are also often the ones that last shorter than others.

I know my best friend since we were kids.

I’ve been in romantic relationships with people who I really don’t care for now.

My kids will always be my kids.

Your post and comments seem to indicate that you have never felt any real attachment to someone that goes beyond infatuation.

If you are 15, that’s ok, you’ll experience real friendship in time, and if you have kids you will understand what that means.

If you are 30+ and have kids, you seriously should book an appointment with a good therapist.
