how do i deal with the situation?

i have a girlfriend that i like alot but i think she's still in love with her ex girlfriend.

i think i could be a rebound but it feels like she love me more

and yes i'm married and my husband knows about her.

she says that her ex is trying to make up with her and she doesn't want to turn her down yet because its only been 6months since they broke up and she was waiting for their reunion before she met me.

now that i'm here she says she will wait to know if her ex gf is just doing this because she really wants her back or if she's doing it because she's now seeing me.

i feel like i'm being played but when we're together i want to stay with her.
