I also am not looking for a relationship. In fact, I am militant in my avoidance of them at this point in my life. However, some things are not entirely in my control, and I can't say for certain that at some point in the future that I won't meet some woman who just leaves me breathless with how awesome she is.
I used to be really attracted to the good looking women, but it wasn't mutual. There have been women over the years who were attracted to me, but it wasn't mutual. The women I ended up in relationships or marriages with were compromises about a lot of things and they were "good enough". Good enough was NOT good enough. I can settle for a lot of things in this life, but love is NOT one of them. Love had better knock my socks completely off or it just isn't worth it.
I cannot fathom getting married again, so I'd be looking for a platonic companion if anything. A gal-pal.
