Search Results: love triangle

I am sleeping with this guy I met a while, it's completely casual, and I have no problem with that ( so far) let's call him 'a', but I very recently was involved in a painful love triangle of sorts?

I had feelings for this amazing guy 'b' and I let him know, because I feel as if that's the decent thing to do! But he let me know that he actually fancied my best friend.. And while this was undoubtably awkward, I tried to be happy for her, incase she decided this was something she wanted too..
Now, the thing about me is; I get attached veeerrrry easily. B was somewhat an asshole with the whole crushing situation, he understood and respected that I had feelings for him, but let me know that was not even an option..

So I was placed in this very awkward situation with my closest friend and the guy I liked.. She eventually let him know that feelings were not reciprocated and her and I managed to patch up our friendship rather quickly.

I then joined tinder and slept with a guy I've known for years (a)
I feel as if this is somewhat out of character for me? And I am unsure whether my feelings for b still remain.

In addition to this, a was the first man I've slept with since breaking up with my ex over a year ago.. so this was not something I decided to do without lots of thought.
I'm just confused and can't process my own thoughts... advice or a response is appreciated.
