and I hate myself for it, but cant just turn it off.
It started out just harmless flirting, im flirty anyway, and am so with all of his friends, but with him there and never would be if he wasnt. He knows I'm a little bit of an attention seeker and a bit insecure so attention is nice. this would be fine but the problem is there's chemistry with this guy. And I think he likes me too.... DPs other friends joke about the fact that he likes me, but they obv dont know that I kinda like him too...
I would never do anything about my feelings, would never act on them, but I like his company because of the excitment from the chemistry. for example, I quite often go on nights out with DP and his friends, and me and this guy always end up walking home together a wee bit in front of the others, just chatting, but obviosuly we have both singled out eachother, intentionally or not.
the thing that has made me feel seriously guilty is the other week DPs friends were all round, and drinking, and me and this guy were holding hands onder a blanket. 
We talk on facebook chat quite a lot as well, nothing is ever said about anything more than just friends, but its obvious that its there.
I know I should just avoid this guy until I get over my feelings, but its so hard, because DPs are my friends IYKWIM? so avoiding him would mean losing my social life, (and the selfish attention seeker in me doesnt want to lose the thrill..)
Help me, what do I do??
