Kissed my best mate

Hi all
I need some advice.
I work with a guy I went to school with, were both 25. Didnt really know him in school but he recognised me in work about 5 months back and we became real good buddies pretty much instantly. We spend every break/lunch time together and most evenings we hang out in pubs together, got to know each other quite well.

When I first met him I had a boyfriend (who I broke up with a month back) so I never had any interest in him other than a buddy. He is such a dog on heat too; he pretty much letches and comments on EVERY women we've seen! Which I find hilarious. Hes pretty shy in terms of approaching women but he seems to want all of them :-D ! I've tried to set him up with some women in my department too. Hes a cool guy and has pretty much turned into my best mate.

Anyway, last Friday night we were hanging out in my garden having a few drinks, he put his arm around me then kissed me, we had an long chat after with him saying he really likes me and had to tell me that night (he has mentioned a few things before indicating how he felt but I never really took much notice), he said its great how well we get on, he's never been so comfortable around anyone. He said he needed a few drinks to be able to tell me all this as hes really shy when hes sober and wouldnt have said, so not to expect him to say it again if he hasnt had a drink but to know he means it.. Which is difficult as im that shy too!! He left at 4AM, we spent an hour at the door just not wanting to go and all that soppey stuff (-;

So- since this- back in work- and I have locked back into friend mode and haven't been able to discuss it with him lol! I'm acting as if nothing happened and he is too (apart from he isnt drooling about other women now ive noticed!) Its so so strange, I see him as my best friend still that perves over women constantly and I cant seem to forget how he is, in terms of a partner its such a turn of being aware how sleezy he can be. On the night we kissed I brought this up and he said if he's with one person he wouldnt be like that as "he'd had someone to focus on".. Is that how it works?!

On the Monday back in work he said he had an amazing night Friday, but thats all thats been said about it since! Weve been to the pub once this week for a couple of hours but we just had normal matey chit chat. Oh he did text me last night and said he missed me but I know he had a few drinks when he sent it.

So I dont really know how to play things now, he's giving as little away as I am about it, ok maybe he's giving away a little and i'm keeping all zipped. But I dont really know how to be round him other than matey!? Maybe he was just drunk and horny when he said all that last Friday and feels awkward now as he regrets it but is still texting nice things so I dont get hurt? I do really like him, his sense of humor is amazing and he's good looking. But as weve been friends for so long now im struggling to click into seeing him differently.

Today I didnt hear from him all day which is unusual, for 5 months he always sends a morning text to see what times we can meet for the day. I kind of want to go out with him tomorrow after work and spend some time together again but I dont know whether I should ask, maybe he wont as he doesnt think im interested?!

Ahh I dont know help!!!!
