<human>: I(f,30)´m in a relationship with a really nice guy (m,32) for 6 months now. I like him, he makes me laugh and he cares for me. He could be the perfect partner for me. Only one thing is missing - the "big zing", but that was okay until now.

Last week everything changed. I met an old "crush" (m,30) from years ago. (At that time me both were in relationships with other partners and we decided to ignore our feelings for each other. We stopped meeting and talking, which was quite hard. Anyhow I couldn´t forget him).

When we met now again we talked a lot - mostly about us and how it used to be and could still be. Now I think about him the whole day again, which is really confusing, and which shows me, that I love him and cannot forget him.

Is this our second chance? How important is the "zing" for a longer relationship? I´ve already tried to forget him one time (more/less successful). I possibly can do this another time.

What would you do?

Thanks für your opinions and advices.

Can you provide a brief overview of the text?
<bot>: I have to choose between a relationship with a "nice guy", and an other guy, I cannot forget for years and returned now in my life
