People begrudge me having a girlfriend

I have the feeling, that people around me don't like it, when I get the chance of having a girlfriend.

This happened a lot in the past: when I get along well with a woman and get the chance of a romance (and this doesn't happen often), people around me ruin it.
For example they start talking bullshit about me, let me represent as a bad person, so that the woman distances herself from me - I think she became unsure because of that or feared about her image.
Another example, they dragged me from a woman with the reason "we need another player for the game!" and I resisted because I had a great conversation with her (that was on a trip in England at my time in evening school). But for all that they dragged me with all they have from her without special reason - I guess they were jealous because later I found out, that they said something like "seriously, he didn't deserve her" or "It's the best for her".
That frustrates me very much. I find a woman, the chemistry between us is right and then BOOM! - it all goes worst because some people don't like to see it.
I know, maybe it could be possible, that the woman herself is an idiot that she believes that, what the idiots say. But I can't imagine that this is every time the case. And most of all that happens, when the woman is attractive.

I don't know how to handle this. It is fucking annoying and frustrating. Any tips for me? Do I something wrong?

PS: I hope this section here is the right category for my problem - because it has to do with some kind of dating. If not, I apologize for that, I'm new in this forum.

 

@mcgrim that's why I'll never understand their motives. I mean what's the point of doing that, can't they just care about their own business? I'm rather a person, who don't give a fuck about who is in a relationship with somebody.

Idk, maybe meanwhile I'm too restrained and conservative to other people and maybe I wear clothes that don't fit to the normal. What do you mean with boundaries?

@TheBigBadWolf hi there! Yes, sometimes I thought, I have a behavior they don't like. I changed it, make it different then before. Maybe the mistake I did was after the bad behavior: I changed it to a conservative behavior - I thought, I couldn't do anything wrong with it - but it changed nothing.
But your message helps me very much, thank you bro!

@Temujin I noticed that they are not my friends, most of all this happened in evening school, education and sometimes on festivals. But also it happens sometimes in university. The only true friends I have are far away and I meet them only, when I make vacation or visit a concert of bands and see ma friends.

 

I cleaned my "friends-list" after I noticed such idiots. However that also means I become more and more lonely, but I guess this can be much better then having friends who makes me sick.

 

But this jealousy seems to be very hard, if they bedruge me having a girlfriend. But some of these people are better then me (have a job, girlfriend, a hell lot of money, travel where ever they want etc.) and still bedruge me - and I don't have any of these options because I study.

 

As I told before, I removed these people, who bedruge me. The few "true" friends, which are left, lives far away from me, either in a different city 300 miles away from me or in a different country.

I have a few hobbies, that make me feel better, for example videogames, festivals, Capoeira ...
But everywhere you have one of such dickheads, that ball you up.
