Sometimes people are just bad at responding to texts or emails, so you have to take that into consideration as well. For example, I'll text my mom and she'll never text me back. It's not that she doesn't love me; it's that she's very forgetful and doesn't remember reading my text. Or, sometimes she doesn't read her phone AT ALL. And I don't even bother with voicemails with her because she won't check those. I have to call her to get her attention. It sucks, but she does that to my sister and dad as well; it's just how she is.

I will admit, though, that I've texted people and they purposely never texted me back, despite them texting a billion other people instead. For example, one "friend" of mine stopped texting me one day, and another person I knew said, "I'm so tired. I was texting [insert name here] all night long instead of sleeping!! We also FaceTimed!!" Then I said, "oh, haha. That's cool." They said, "Yeah. We're planning on going to her party tomorrow. Did she tell you when it was?"

So, I think it's probably a combo of both for you -- some people being bad at responding and others not caring to respond.

I know it's hurtful when people purposely ignore you, but you don't want to be friends with people who don't care about you anyway. I'd personally rather have NO friends than "friends" who take advantage of me or ignore me.

As for those who unintentionally ignore you -- I'd say don't put too much effort into maintaining the relationship, whether it's a romantic one or a friendship. Relationships in general are give and take. If you're constantly giving, you may find yourself frustrated to no end, or at the very least, burnt out.

In my case, I can't always tell if it's my bipolar interfering or my terrible social skills. If I'm honest, though, I'd say it's likely a bit of both. But sometimes it's not even my fault (as far as I can tell). Some people just find reasons to dislike someone. For example, "ohhhh, Johnny ate McDonald's the other day? He's clearly an animal abuser and animal killer!!! I bet he beats his dogs!!!" I mean, that is total B.S. because eating McDonald's does not imply animal abuse, but some people are like that.
