My bf and I live together. I went home for a month. We kept in touch every single day. I came back without telling him to give him a surprise to which he didn't even react anything. He didn't smile nor was shocked. When I came inside our room there was nothing suspicious or out of the ordinary. But then as I was laying down in bed there was a red long hair on the pillow and my hair is pitch black. I asked him who came over he said a guy friend came to meet him. Then I questioned him whose red hair was it. Then he said "It must've been his girlfriend she also came with him" which is weird because he didn't say anything about anyone's girlfriend... And he told me something very ridiculous "You would've been mad if I had told you a girl also came over" I mean why would I be mad when it's his friend's girlfriend?!
I don't know it all just feels iffy and I can't say he's cheating on me and I'm not sure he's not either.
