There can be a multitude of reasons for a guy losing interest in a girl. The most common reason would likely be the guy has found or has feelings for a different or new girl.
Other reasons could be being bored with the girl, the girl doesn't share the guys interests, the newness of the relationship is over etc.
When a guy loses interest on you, it means that the two of you did not square with each other, and he found it appropriate to drop you, and accepting and moving on is always the best way to go about it.
If the girl has another guy on her mind chances are slim for the first guy. The one thing the first guy can hope is that the girl loses interest in the second guy.
When a guy who is a friend starts avoiding you there can be a few reasons. Sometimes a guy just loses interest, and sometimes if he like a girl and she is with someone else they become distant because they want to be in that relationship.
Yes because most of the time the guy is obsessed:).!
Yes. The guy is showing interest in the girl by giving her a proper goodbye.
It depends on the girl. Sometimes it makes the guy look tough and sometimes it makes him look sweet.
if they loose interest in you
Well if the guy is always staring at the girl then she thinks something is wrong. And maybe the girl has no interest in the guy if she doesnt show the slightest interest which means; not talking to the guy, not looking at they guy, ignoring the guy the girl is not into you. But is she pays attention to you theres a chance she thinks your sweet or else she wouldnt be talking to you. If a girl says something mean dont take it as a threat . Give the girl some space she might not be ready for a relationship.
because it makes the girl look desbret
Whatever makes you feel comfortable.
Bisexual and polyamorous
Absolutely not.
This is the 21st century, race isn't an issue anymore (or at least it shouldn't be). If you want to be with someone of a different race then go for it, no one will look down on you and if anyone does then forget them who cares what others think. If you and your person of interest (i say person because guy+guy, girl+girl, guy+girl, girl+guy doesn't matter to me and shouldn't matter to anyone else) want to be together then that's all that matters. You should always do what makes you happy and what is the right thing to do.
