Why don't I have any friends?

Hi, I'm a 30 year old, attractive, easy to get along with person. I recentlty got married in 2009, and I feel as though my friends don't like me anymore. I have been close with 2 other girls for about 10+ years. (one of them I have been friends with since kindergarten) I was a maid of honor in friend # 1's wedding, and a bridesmaid in the other's. Anyway, in 2008, one of them decided to get divorced. Of course I was a little disappointed, and told her I thought she should really think about her decison, but I let her know that I supported her in any way possible and that I was clearly on her side. I have to say that I was really hurt when began confiding in the other friend of ours more than me. I was totally kept in the dark during the whole process, where I didn't know ANYTHING!! While it hurt, I was respectful and gave her space, not calling her too much, or asking too many questions. So, these two have grown really really close during the last 3 years, distancing themselves from me totally. I got married in 2009, they were both in my wedding, one of them left my wedding early.......she was the maid of honor! (I was pissed) My bachellorette party was basically thrown without any effort, nothing like I have ever thrown for them. (they have money as they are both teachers) Now friend #2 is getting a divorce too, and same thing......I know NOTHING! I don't even know who these girls are datingnevermind anything else. I own an insurance agency and they have NEVER stepped foot in my office to get a quote! Honestly, I feel they do not like me, so I don't push my way into their little twosome/divorcee/teacher bond. What really made me confront them was last summer Lady Gaga was on tour, and they told me they had bought tickets with another group of girls, and were getting a hotel room, limo, dressing up to the 9's......going all out. I said, "really, thats nice I would have loved to go!" One of them mumbled that they didn't think I wanted to go. At first I wasn't too pissed because I figured they didn't ask me bc I am married now, but when I found out that other girls who were married were going, I flipped! We didnt talk for a few months after that, but now we sort of made up, but still I never talk to them, I know nothing about their lives and they know nothing about mine. It's like an empty shell with nothing inside! Why??? What is wrong with me??? What did I do wrong? I have been so down about my horrible social life, I reached out to some old friends I knew in highschool but have been rejected by them as well. I invited them to my 30th birthday party, and no one showed up! I let that go, rationalizing that maybe they don't feel comfortable coming bc its beeen a while. I went to dinner with them a few weeks later, and had a great time. Just yesterday, I saw pics on FB of one of their wedding showers, that I was not invited to! I guess I am really living in a dreamworld about friendships! What am I doing wrong? Please advise. Sorry so long!
