i know i might be a female but that kind of thing happened with me before sort of.
my best guy friend told me he liked me and he had been dating this girl for like 7 months and i liked him too, regardless my stupidity got in the way and i let him take advantage of me while he was still dating someone else and then he broke up with his gf for me and we went out for two weeks and he did the same thing with her when me and him were together. But from my experience, if you're ex really did love you he wouldn't even be with another girl, and he should've contacted you immediately after you got home from your trip or from being abroad, ya know? if he says he loves you and he's with someone else and he hasn't broken up with that person yet, don't bother, i know it hurts cuz you love him, but he's most likely going to hurt you and his current gf. He's not worth it, he's basically saying, 'oh if i'm dating someone else and i like my ex gf still maybe i can have both'. If he really wants to be with you he should just dump her, but the truth of the matter is he hasn't broken up with her and he went behind her back and told you that he still loves you, who knows what could happen if he was with you and she was still in his mind. Trust me, it's not worth basically fighting for someone who previously broke up with you.
Ich liebe meinen freund.
