..and unsure how to reconcile.

I've been dating successfully for the last couple of years since finding TRP. Slept with a few dozen women (mostly Tinder) and became utterly jaded with casual sex. Fell into a couple of short relationships during that time, but always with the wrong person, so I broke up with them.

Recently I met someone in Thailand (Myanmar chick) I've been seeing for a few months, 23, virgin (seems that way from experience with her, too), she started to fall pretty hard, but she's young. Definitely a "fuck yes" if we're running by that rule.

I'm open to a relationship, but I'm also open to having more fun. She can be replaced, so there isn't a oneitis per se.. but I do find myself unable to invest in a relationship knowing what I now know about women, and yet the alternative is vacuous eternal plating. I'm 30 and I would like children one day (no marriage), so I have to figure this LTR stuff out. -- but from what I've read and seen, the only certainty is she will leave. The question is just when. How are we supposed to even attempt to raise families under that premise?

Any insight? Advice? How am I supposed to make any long-term plans with someone or emotionally invest in them at all with a RP lens on life? Every time I start to invest or start to measure them up for long-term potential I feel like a tool being used.

Just to note - I am NOT talking about a family with this particular woman. I wouldn't consider a family with anyone until a good year or two after the honeymoon period. I'm talking about relationships in general.
