My need to complain

Remember how I said that I needed to get used to having someone in my bed at night. Well in the past 3 weeks we've only been apart at night 4 times. Last night being one of them. Suffice to say I have gotten used to him being there and last night really sucked. He was supposed to come and take me out to dinner but things happened and that never happened. He ended up getting stuck talking with his dad and I told him to call when he was done. I spent the evening talking to my roommate and then I noticed it was 10:00. So I get ready and climb into bed at 10:15. I call him to say goodnight and wake him up. He was already sound asleep. I had a hard time falling asleep and spent the night tossing and turning. He sent me a text this morning saying that he missed me, but it doesn't seem that he had hard time sleeping without me there. I'm not mad just a bit sad about it. I was lonely and he was fine. FUCK! I know he loves me there's no question there, but now I'm starting to second guess and worry again. Not good. I just have to keep reminding myself to take this one day at a time. I over analyze everything when there's nothing there to worry about. I have got to stop that. That saying that "you don't what you have till it's gone". Well, I know what I have and last night he wasn't there. It's much harder when you know what isn't there with you. My biggest concern is that he has told me that he's a heartbreaker. I just don't want it to be mine, but I also don't want to live being guarded all the time. One day at a time. Right?
