Sabotaging my own relationship

This is my first post on Reddit, so sorry if I'm doing it wrong. I just need to vent. I'm a 26 year old female and I have had pretty bad social anxiety for as long as I can remember. Even when I was a kid, I was terrified to call my own friends on the phone to ask if they wanted to hang out. I never spoke up in class and was thought of as a "goody goody." I've always been introverted and studious, but nice and considerate of others I interact with. Well, I've been with my current boyfriend (also introverted, though more outgoing than I am) for about 6 months. He's really been great to me and I'd say it's going well, although it's going more slowly than relationships I've had in the past (he hasn't told me he loves me yet, and I still feel like there's a little bit of distance between us).

The problem is, I can't stop crying in front of him. The other night I watched "Ted" with him for the first time, and I found myself sobbing when Ted got ripped in half. Last night I did his laundry and made him dinner and he proceeded to eat it at his desk while playing a computer game and completely ignoring me. And he continued to ignore me for the rest of the night. I finally cried myself to sleep because I was so upset that he couldn't stop his game for half an hour to interact with me. We talked about it and he apologized but I just couldn't get over that feeling. Today I keep randomly crying and I even had to leave his kickball game early because I'm still upset. This sounds ridiculous even as I'm typing it but I can't stop feeling sad.

Maybe related to this is that I've found myself almost avoiding people I was once very good friends with. I see these people at work and pretend to be busy so that I don't have to eat lunch with them or talk to them. Not even sure why; it's not like we had a falling out or anything. Consequently I've been losing several good friends and have gotten progressively more lonely. Anyone have any advice? I'm feeling like giving up. Thanks.
