You should ask his reasons for staying single. If they are not good enough I wouldn't consider him worth worrying about. If they are good reasons, you still shouldn't feel you must wait for him. If someone better comes along, go for it!
Good luck!
The best thing to do, is just let her have that time and be single for a little while. You stay single to though, and you both can still talk, call eachother, send e-mails, but just let her stay single if that is what makes her mom happy. The only thing that matters is that she loves you, i know it may be hard, but if you want everything to work out good, that's the best thing to do. Goodluck, hoped I helped, :)
Ask him why he wants you out of the picture, maybe he feels guilty having a girlfriend.
they should stay away from each other for a while like separation until he figures out what he wants and if he loves her enough to wait and be alone for a while to see if the attraction for her is back if not then and he knows she love him he should be honest with her and let go so they both end up in healthier normal relationship
Talk to her about it. See if she really wants to be with you or date other people while being with you.
It depends if you can face being second best. She still has feelings for this other person, and the fact that she has these while she is still with you shows you that you do not have all the qualities she desires. Perhaps break up for a little bit until she knows what she wants.
You should think he's not "your guy" anymore and move on with your life.
it means she really LOVES you she wants to have every thing for the twoof you
The guy tells you just only because he wants to know how you will feel towards it.
dump her and forget about it. or do the same.
Evidence is that his "unconditional love" is fickle.
This guy doesn't know what he wants, and has zero communication skills to be honewst with you. Move on to someone who has more to offer you.
Discuss it together and find out if you are both ready or if you should wait a while
