Context:

My current LTR confessed (of her own volition) that she visited her ex twice after they broke up and before we met. I originally plunged into this LTR because her N-count was extremely low (2), but given this knowledge I probably wouldn't have, especially since the second time she visited him was only a few weeks before we started seeing each other.

Questions:

How does sleeping with an ex contribute to a girl's SMV (better or worse than a ONS)?

What would you do in my situation?
