Have you ever gotten bored in a relationship?

So I got out of a relationship last month and we were together for three months before I started getting really bored. Like it's not the sex or anything it's just the repetition of seeing him every day and every night for months. And now I'm starting to date again and I met this guy and he's cool and he asked me out and I'm already getting bored again. I don't know what's wrong with me. It's like every time I get into a relationship I get bored and leave. Anyone else have this problem?
