Crazy psycho thanks to period hormones

SOOOO let me start of with I’m an incredibly chill relaxed person. I hardly get emotional about much let alone jealous or petty. I’m confident and smart so at any point if i feel like I’m not getting what I deserve I sure as hell won’t take it. That being said I’ve been with my husband for 7 years married for only 1. In these 7 years we both have grown so damn much! I was a bit of a basket case when he met me, I was needy and yet still I knew when I was being treated badly and didn’t take it. (So Sometime I did overreact though however I did always apologize) well 7 months into our relationship I found text in his phone that was him flirting with a girl he used to be interested in. Well I fucking broke down went through all his shit made sure he wasn’t cheating, broke into his Facebook so on and so forth. Well to end this I waiting a few days until it seemed they hadn’t been talking and I went into his Facebook blocked her and went to his cell and did the same. Then I became a super sexy vixen / perfect gf for a few weeks until I was sure he hadn’t been talking to her and we went about our normal relationship. Fast forward we are 7 years in happy loving relationship (much more mentally stable)We never fight, we are great with communication and work well together on many projects. BUT I HAD THIS HORRIFYING dream he cheating on me with that originally bitch I block all those years ago! I freaked went through all his shit phone, Facebook, email so on and so forth. Nothing no evidence and he even surprised me with dinner he cooked last night. There is no reason for me to think this of my incredible loving kind husband but 7 years later I still can’t get it out of my mind. Maybe it is because she’s the opposite of me tan, light hair, green eyes big boobs tall. I’m pale, short, brown hair and eyes and thin frame no boobs with a lot of ass. I just feel so insecure and crazy because he is amazing and always there but this one slip up still has me fucked up thanks to crazy hormone driven dreams. Thank for the rant (AND I REALLY DO THINK IM WAY PRETTIER THAN HER, however he is a boob man and I have none so it kinda hurts that maybe he doesn’t find me attractive enough)
