Hey man, if I were you I wouldn't take it to heart, just make sure your friends know your intent, my mates know I'm a whore and leave me to it if they see I'm getting along with someone.

If they're all in LTRs then just explain your situation, from my experience almost every situation when there is a mutal respect but some kind of conflict of opinion it can be resolved by explaining your intent and having everyone understand the situation fully.

Miscommunication is the cause of almost all of these kind of situations, don't ditch your friends to be a loner or to hang out with 'puas' that's not what this is about. Explain your situation and if they're worth having as friends they will listen and agree or advise you on what they think.
