I get upset when people don't want to hang out with me. Can it be related to my parents divorce and fearing abandonment?

I usually try to get people to hang out. When I don't hear an answer it makes me feel anxious and I don't know why they aren't answering. Some people have told me I need to stop calling or texting so much. I guess I'm being that annoying needy person. I wonder if it's related to my parents divorce and fearing that I'll have the same kind of abandonment if people don't want to hang out with me. I think it's on a very subconscious level. I don't know if that's the reason but I feel it is.
