GG my gf left me after a bit more than a year of relationship.

I met her when she had short hair and was overweight and in a bad situation with her family.

I accepted her many flaws, gave her support, and encouraged her to lose weight and to grow her hair.

Now she became a pretty woman with almost 1meter long hair, but the gained new confidence of these changes made her become arrogant and superficial, and she recently dropped me. Probably to have some sexual freedom and enjoy what she never was.

Now I'm lazy to restart the whole process with someone else, so I would like to find someone with already long hair. I've tried dating apps but girls are superficial there.

Any idea of how to find a partner for long term ? (I live in western europe)
