What can I do?

So love can make you blind. It allows you to only see the good in people and sometimes you completely ignore the bad parts. I'm not going to lie I'm so into my boyfriend I think about him all the time and I over analyze a lot of the things he says. Lately it's been hurting me a lot because I take a lot of the things he says to heart and also the things he doesn't say. How can I distract myself and protect myself from getting hurt?
