Answer If you love someone who is already engaged then be a man or woman and move on in your life. Would you like it if someone came along and ruined your relationship, I bet not so why do it to someone else. Surely there is someone else you can fall in love with and not destroy a good relationship because you want your own way.
Get out or stop.
it is always better to have a relationship with your parents be4 someone else ypur parents are the people you can look up to when he/she breaks your heart :DDD
Find someone else.
if he's dating someone else he's not worth it, leave him
Tell him you want to ask him something,ask him if you are friends,then,hell take it from there
You probably miss being in that kind of relationship, Or maybe you want to be his/her friend.
