Im too shy to talk to the girl I love, girls can you help please?

Sorry for this being so long: I met this girl four years ago and I immediately fell in love with her. She is so beautiful sexy and I love her personality. Since then we have become very close almost like family because her family hangs out with mine. The first three years we have talked to each other on msn everyday if not every other day and we have alot in common. We have become so close that we can tell each other anything and will always be there for one another. Iv always had feelings for her and I think she has feelings for me too. Once friend and I went to get lunch and he told me that the girl I like thinks I'm hot but she didn't say it to me directly. She also thinks I'm sweet and kind person which makes me really happy. She used to stare at me and smile when we hang out. Currently she has a bf of 10 months and a job so I hardly see her, I still want to be with her but for the past year I have been only seeing her once a month because I'm scared of talking to her and reinvent the relationship we once had years ago. We are still close but I hardly see her and it makes me sad. The last time I saw her was at night when she was wearing a tshirt and sweat pants with a black thong on about to go to bed so I took walk to her room with her and I gave her a hug and kiss goodnight as she looked at me and smiled I told her I love her and she replied " I love you too". I have become so shy and scared of what she thought about me I apologized to her for acting so weird and tring to impress her. She said that I shouldn't because I'm a nice guy. I really want to get back into thing and start talking and seeing her reguraly again but I'm too shy and i don't want to go on fb because her bf is keep talking to his friends on how much he enjoys ******* her and licking her pussy, which gets me really upset hearing that everyday. I try texting her but I always end up texting her during her working hours which could get her into trouble. Could someone help and don't judge ?
