Do i leave her just for him?

Ok here my problem is I have a good relationship almost 3yrs, this girl is the one that I love... Everything was so GOOD for us, but 4 months ago we met a guy in church seens they get their cell num. Everything change for bad to me. They talk on the...

phone for hours, we have fights for that. Now she saids that she's Not sure to be in love with me. What can I do? Do I leave her? I know this guy likes her. I don't know what can I do. Please help!!! Thanks...

option 1: if you want to stay with the girl, then you may want to just spark the fire and give this other guy a call on the cell, yell at him for a while, and once its all over with, your girlfriend will end up choosing one or the other, keep in mind however that with this tactic you will end up much happier or much more depressed depending on the outcome, so you may want to take your second choice.
option 2: have a civil talk(not a fight) with the girl over this guy, tell her very plainly that you love her and want to stay with her forever but if shes going to talk to another guy all the time that they cannot stay happy together and someone's going to have to give in and break the relation.
option 3: find the guy and turn him into human pulp for taking your woman.
option 4: lose the girl and find another one.

these are the only options that I can think of, sorry if I wasnt of any help, if you need anything else, fun mail me, ill be here for a little while longer.

You need to ask her what she wants. If it the other guy you will have to let her go. If shes the sort of chick who likes other guys while she is with you, you dont want her anyway. Find someone who loves you more than anything.
