hi there.
I'm looking for some advice. well not only that i need to get this out of my system as i cant really tell anyone.

im in a relationship and we have been together over 1 year now. we are engaged and have been since valentines day 2010. i was still very happy with my current partner, until a new supervisor started at my job. i have found myself becoming very attracted to him. he is such a lovely man, he puts everyone before himself. but thats the problem, he puts EVERYONE, not just me. i dont know how he feels and to be honest hes never really shown any attraction back to me, nothing different than he does with everyone else which is his way of being a good supervisor. i love my current partner very much but i cant help but think about 'Lee'. one day last week in work i complained about my current partner as i am in the middle of learning to drive and am studying my theory - my current partner was hrrible about the fact that i was asking for his help, and when i mentioned it to 'Lee', he began to help me through out the day by doing silly things such as drawing road signs and shouting, 'What's this one?' hes just so lovely!!! it doesnt help that i am doing a charity skydive with him in the next few months which is through raising money for work. it also doesnt help the fact its me he has decided to chose to do it with, simply because i said i have always wanted to do it, he said he would do it with me. is that him being nice because he has to or is that actually him? i keep trying to tell myself that nothing is ever going to come of it(which i dont think it will) but it doesnt help the thoughts and feelings going through my head. i see him almost every day. i dont know what i should do. its unfair on my current partner but i cant help it. ARGH!

any advice as to what i should do or anyone in or have been in the same situation.
thanks guys x
