if you love somebody, and he/she loves you too. But No sex involved.

or

if you had sex with somebody else, other than your partner?

i've had a relationship with a woman who has anger problem from her past. In the beginning, everything went well. But then, after few years, her anger problem came back and started to give me health problem. We broke up.

then i started a new relationship with another woman. Psychologically and mentally damage from her past too. And she ended up destroying my life. We broke up.

I understand that once you broke up, you'll feel lonely. Me too.
But I have to agree,
Anybody should work on their own problem first before deciding to start a new relationship, otherwise it's just gonna be another drama.
