Please I need advice in this relationship
Don't call me crazy because this is not common but possible I think. I'm 21 and I I've been with my high school sweetheart since I was 17 we are Bestfriends like we're married or something. We know everything about each other. Once she cheated on me broke my heart she only kissed this guy ( she claims) but we got passed it. I love this girl anytime we fight my heart gets heavy. I may be crazy but I can't shake this feeling. Her mom is married to a man who isn't her father. From the beginning idk why but I caught the feeling that her moms new husband and her were having s**! I've had dreams about it and no I'm not psychic but 1 or 2 of my dreams has come true. She talks about him all the time and it is p****** me off. I forgot to mention when we turned 18 we lived with each other we just moved apart a month ago and the fact that they are under the same roof again is driving my suspicion crazy. Sometimes like I don't hear from her for hours but she claims she's doing something or busy. Again she doesn't go a day without mentioning him she doesn't talk about her mom this f****** much. He looks like a creep that would do that. What tf do I do she knows that something about him is bothering me but she doesn't know what I'm so sure that this is happening that I just want to leave the love of my life. I'm a crazy I know I'm somewhat insecure but what do I do?
