I have met this really nice guy ( we've been friends for a while and if my bf finds out hed flip) who wants me to break up with my bf and to start a romantic relationship with him. i no my bf loves me and i dont want him to hate me, hed b devastaded we split.I cant stop thinkin bout this other guy and he calls me all the time, how should i handle this situation?
When you break up with him do not do it for another guy. Spend sometime being single and enjoying your time that way you will feel more settled when another comes along.
