Not feeling myself

Does anyone get in states where they just feel bleh towards their relationship and boyfriend. I don’t know what’s going on. I’m acting really stand offish with my boyfriend, like I don’t want to talk engage in conversation when texting, I’m not excited to see him nor have this fire to do the deed like I normally do, he’s kind of getting on my nerves a little. I have like I’m just being a bitch. I just don’t know the reason. It almost feels as though it’s pms but it’s not.

I haven’t seen him for a while because of life getting in the way so I don’t know if I’m just frustrated deep down, I’m just really confused.
