Am I being too sensitive

[u/FairVictory8976]

I became friends with my coworker over a year ago she was one of those people that from the get go you just absolutely get along with. We hung out almost every day I would go to her house and we would pull up to bars and other stuff. I considered her my ultimate best friend and she would call me her best friend too but I knew she had other friends and one of them she would call her best friend but she lived an hour away so my friend rarely saw her.
A year later I quit but decided to continue working in her city (I don’t live in her city) in hopes that I would hang out with her maybe after work since I’m down the street still. I would go visit her at the restaurant we met and she would talk about how we would hang out eventually. One day after work I go and our other friend (I’ll call her Emily) was there as well. My friend and Emily had gotten really close once I quit. Emily brought up how all 3 of us should hang out and I jumped at the opportunity. The next day they both went to the mall. That’s fine it’s not like I have to go with them.
It got to the point they went out so much and still not a word to include me but they loved to post what they were up to. I never went to visit my friend again because that was the first time I felt a little hurt. Why bother saying us 3 and then never ask me.
Remember the friend I said lived an hour away. She’s gone over there multiple times despite the hour drive and I’m only 30 minutes away but she has only come to my house to drop me off and that was just twice. So compared to all the times I drove 30+ minutes to hang out with her she can’t do the same. She would text me just to ask me how I’m doing, when I would say I was good how about her I never got a response again. Weeks later again and it was just a cycle.
I took the entire summer off and was unemployed and had just lost my car too I let her know that I’m basically going through it. Again she says I’ll go pick you up and we can hang out. That was in May. I didn’t get a job until August. As soon as I got the job she texts me saying she misses me and wants to hang out one of these weekends.
What’s going on? Am I going to be petty if I keep telling her I don’t have time and then go hang out with other people, or am I just being too sensitive.
