She wants to be ur girlfriend, and wants a closer relationship. She wants to be closer and wants things.
Then she wants to continue being friends with you.
she wants to be with you forever/ your relationship is forever
if you really love her, go along wit watever she wants
In my opinion she wants to protect you from hurt. As she is bisexual so she might not want that you feel bad when she shows love towards both the gender.
I would first try to find out why he wishes to break up with his girlfriend and then continue from there.
It could mean that she just wants your relationship over and done with.
You can't have it both ways and it is not fair or right to settle for your current girlfriend while waiting to know if this other girl likes you. You are in a relationship as well as this other girl and you should not do anything about this - she is with her boyfriend because she wants to be - let her be and either continue your current relationship or decide if you want out.
Ask him to be honest with you. If he's a good guy, he will.
Probably wants to continue the relationship but without a commitment,
You should expect to move on. Even if her relationship with her husband does not last, she likely still will not want to marry you or continue to be with you because she still wants to be with him and/or she feels you betrayed her, as ironic as that may sound.
If you don't feel comfortable then do not have an open relationship. You should talk to your girlfriend and explain. Maybe she needs time to think about her feelings.
