<human>: Can you succinctly summarize the text in 1-3 sentences?

Hey reddit, I'm seeing a guy and when we first started dating, he would blow me off- make plans then not text me back for days or show up ridiculously late (hours). This happened a few times and i was patient with him but after a handful of times, I became really upset with him, and he would just ignore me for weeks. I should've ended things but when we were together, we had a great time and I really really like him. I guess the heart wants what it wants.

He has a lot going on and I'm not just saying that; I was a witness to it. Coworkers were calling him until wee hours of the night. We talked things out and he has been better but I still have this fear that he will do the same thing again. Sometimes, he will take 10 hours to respond back to me and this is very frustrating.

So I freaked out on him and and finally let everything out when we had a conversation and I just want to know if I am crazy and should see someone about this neediness/clinginess or if this is normal given the circumstances? I hate to feel out of control of my emotions and I have this fear of abandonment due to my childhood but also because of his actions at the beginning of the relationship.
<bot>: I am seeing a guy who is flakey and I was patient at first but now I freak out and blow up his phone if he doesn't respond within 3-4 hours. Is this normal?
