I'm in love in another guy, but my b/f love me very much.. what should I do?

Be honest with your boyfriend and let him go, and take your chances with the one you really want.

How old are you?

Figure out why you went withteh new guy. Was it because you felt lonely, angry, confused, spitefull?

If you were Lonely-
find out why and fix it. Most people whoare lonely, even if they are in a good relationship, feel like the relationship is not all that they need, then they feel guilty for wanting so much. They look to others for ratifing themselves.

Don't do that. Find happiness within yourself and contentment in the present as you hope for the future and understand that the only things between most people and true joy is themselves. That is why most folks are unhappy and lonely. They cannot defeat their worst enemy= themselves.

If you are angry
step back and find out why you were even in enough contact with the new guy to even fall in love. Breathe. Take a breake from both of them until you get your mind straight.

if you are confused
once again find out why. Are you in love because you are unsatisfied at home? Or are you in love because the new guy seems to need you more than the old guy.

If you are spitfull,
then take a break from both guys and try to figur out what hurt you so bad to make your eyes wander.
Then heal it. Going onto another guy won't heal you and neithor will hanging with the old on. You need to find your priorites, know what will really make you happy, not who. Then really look at the two men in your life and yourself. And be honest. Most people think they deserve more than they have worked for. All the rest think that they deserve nothing, but work the hardest. Figure out which one you are.

This is common , don't feel guilty . Feelings always change.
Most important thing is to just end it. Don't lead him on even more if you really don't like him anymore because eventually there will come a time where you won't take being with him any longer and its going to hurt him even more then it will if you just end it now.
It won't be easy , but he has to know.

Girl I wish my boyfriend love me he don't he said he like me don't love me but still go with the guy you love
