Hey guys, 
So back in middle school/high school I didnt have many friends, I was a weirdo, the weirdo that works out and sings pretty darn well and plays the guitar. My sexual experience also only started at 17.6 but since I've been going wild. I didnt have a lot of experience with people nor friendships because I think I might have a trust issue. I'm a handsome guy, well, with my beard, I used to workout a lot before I broke my collarbone and tore a muscle, but my body still looks tone. Anyways, whenever people started getting closer, it's either they wanted it more than me, and in response I backed off, or I wanted to go out with them all the time. And when they went out with other people without inviting me I got hurt.
So, the real story. I had a birthday last friday, and it was my first birthday that I actually had the chance to do something, to party and to drink with friends, because I finally had some that were around and liked parties. So I felt like it should be a special occasion. 2 weeks prior my birthday, another friend of theirs has a birthday, and they went out with him 2 days in a row. So I expected they would treat me the same, after all back in the days we were best friends in elementary school (we drifted apart and got back in contact at the age of 19, I'm 20 now).

They told me they want to go out but too tired because they went snowboarding.
On Saturday, a day after the special day, 2 of them went out with other people, and I saw it on their instagram and got pretty down because of it.

I might not be engaging, or be overly hurt, but I just truly feel betrayed because we started getting real close. And although I might not value birthdays, because I never actually properly celebrated it with friends, I still felt as if they should've done something special for me.. 

So I just stopped engaging a lot with them.. and took my anger out on weed and had sex with different women in a row already.. so I'm not in the best place. Btw same things goes with women, either I'm too into them and they're not as much, and I get hurt, or they're into me and I'm not so much. Idk how to change that

Am I an asshole to expect them to celebrate with me? And good thing to note, one of the friends that was supposed to go out with me, but canceled, just opened a group to celebrate his birthday in a month. So.. ???
