Is it me or him

Ugh I'm an emotional wreck everything makes me want to cry or get mad.

Mainly with my so.

Idk what it is but I feel like my so doesn't care for me or love me anymore. So I am being a complete asshole. And I can't fix it. Idk what's wrong with me. This is killing me inside and Makin me want to cry. He tells me he loves me and he wants to be with me. I just don't feel like it's real I feel like there's something he's hiding. There are no signs to him hiding or cheating. It's just something is off I feel it in my gut. It's like my mind is preparing me for a break up or something ... ugh I just don't get why I feel this way. He's done nothing. It's just that gut feeling and I don't know why... anyone have any advise? Or ever felt like this.. I could be pregnant. According to glow I'm 5 days late. But I'm waiting longer to test. I have never felt this way before af. Ever.
