Hey hey,
Thank you all for your replies.
Ok, here is what happened yesterday night:
Went home, he wasn't there, put on some chillout music and decided to make my first homemade pizza (with my own dough of course). Later on he came and said he would go to the cinema with some friends. In the meantime I was struggling with the dough and made a complete mess in the kitchen. He offered to help so we were together kneading the dough and were kind of playful. He decided to stay home and we ate to gether pizza and watched TV. I was bursting inside, trying to figure out what to do next. It was late, got upset and went to bed. No use, couldn't sleep. Then it hit me! I sent him a text message "David I can't sleep". I heard him leaving the living room and coming towards my room. He knocked on my door and asked if I was alright. I told him to come and sit next to me and spilled it all out! I tried to get intimate with him. He said he was very flattered and although he felt tempted he is serious with his girlfriend and he would feel guilty if he did something.
Me, on the other hand, ok, a bit disapointed but relieved because I finally said it! I think its beautiful expressing your emotions regardless of the consequences. I don't believe I will have a problem living with him, he is too sweat to hold grudges.

I'll keep you posted if anything else happens (I doubt it)! Aaaaah!
Question: Should I keep trying? Now he knows how I feel, so I can be myself
or start going to the gym and release the tension, lol!
