AITA for being a bit jealous?

Me (19F) & my Bf (22M) had made plans with my cousin (19M) to go out shopping today (we made the plans Thursday after I got out work). I woke up today with a text message from my bf (who had gone to work) that he had forgot he and his buddies planned Friday to go out to a diff city to go to the mall & just general going out stuff.

Now, I’m not jealous of his friends, I’m more so jealous (?) of the fact he goes out without me so much. I don’t go out the house since I don’t have any friends and hadn’t gotten a job till a couple days ago. I’m not a social person and my bf has even said I should try to socialize but I’m just not able to.

I was excited for today, I wanted to dress up, feel pretty, and get stuff I really needed but instead I’m now stuck at home like usual. I’m starting to think I should give up pitching ideas of going out. He did offer that we go out either Sunday or Monday but now I feel like I don’t even want to go out anymore due to the plans being canceled once already.

AITA?
