I have been talking to a girl that I really really like. And its been going good, until I recently found out that she slept with her ex. Now unexpectedly my first love had messaged me and told me her gf of 2 and a half years is leaving to "find herself". And told her not to wait up for her cause she doesnt know if or when she will be back. I still have feelings for her even though she did cheat on me, but I also have feelings for this other girl. I have no idea what to do. Any advice for me?
