<human>: Can you condense the text into three sentences or less?

I have been with this wonderful woman for four months (known her for a little over a year), and over the course of our relationship I have come to know that I convincingly and unequivocally love her deeply. She's the woman I absolutely need to be a part of my life, in so many ways. This past weekend we spent with her parents, and it was one of the best weekends I have had in a long time. I was prepared to tell her I loved her on Sunday, but she became slightly tipsy and I decided it would be best to wait until we were both sober in our thoughts. Fast-forward to tonight, we're at a party my apartment is hosting. We've both had a few drinks (but neither of us are drunk, and in fact I didn't feel anything at this point) and are on my bed when she says she doesn't want me to doubt myself if I ever tell her I love her. I looked her in the eyes and told her, and she seemed disappointed by it.  She said "I love you too" countless times, but I could tell it distressed her. Love is such a big thing to us, and to her, and she takes it incredibly seriously, and I feel like I cheapened it or made her unconvinced of my feelings towards her by saying it when we weren't completely sober. I'm mortified at myself. She's being incredibly supportive, as always, saying she believes me and that if I say it again she'll still act like it's the first time, but I don't want her to have to do that. I'm so disappointed in myself that she has to tell me she believes me. I want her to just know, and have no doubt. We're not fighting or anything, and she isn't angry. She's quite honestly being wonderfully supportive of the whole matter. I just feel like I screwed up badly. 

This woman is my everything. I would do anything for her. Is there anything you think can be done that would help? I want her to know how deeply I care for her.
<bot>: I told my girlfriend that I love her, but neither of us were completely sober, and now I'm worried she doesn't believe me and that I've cheapened what my feelings mean to her.
