how do you manage if there are two people loves you?

That is really a hard question to answer. but he is right about his realization that he could not maintain the two and has to choose one that is most dear to his heart. I think this will make his conscience clear and happy by doing this to himself. I guess that will also be fair for the one that he will let go since the girl doesn't deserved to be treated like that at all.

well if i were in his shoes, he will chose whoever makes his day happiest... but then again , i can sense that if he chose any of the two, he will not be happy anymore because when he chose say GF1.. when they will be together, he can remember GF2 and still felt guilty about it. Pray tell, if he felt guilty now that he has 2 Gf at same time...i can say that he will just prepare himself for the ultimate consequence.. and that is losing both of his GF. It's always 1+1 =0.

Talking about that two girlfriends,for me it will depends on your friend's decision because he is the only person knows his feelings towards with his two girlfriends. He is the only one could tell where he prefer to give his full attention. It's his conscience that bother him because of what he have done with his two GF. It is not easy to have commitment if you yourself don't know how to take it seriously and honestly because you cannot feel happiness together with your loved ones if you are hiding some lies with them and cheating them. So,its better to choose only one of them and theres a say that you cannot do things at the same time and referring that about love you cannot have two girlfriends at the same time.Your friend should make a decision and he should be firm with it even if there is a person would sacrifice and get hurt. Pains are always counterpart when it comes about loving someone. More power to you friend and may God bless you and your friend.
