Are these fantasies normal?

This ones a little long and interesting. So, I met a guy last year and he’s in the army. My cousin had a bad relationship with someone from the army, she said not to trust them. He pretty much won’t divorce her so he can be paid more. Anyway, I had a fascination about him because the army was so mysterious to me. When we first started seeing each other I was on the verge of sending myself into psychosis and spending some time in a mental facility but he would have never guessed. I would have weird crazy thoughts about him. I would think that he would secretly sneak into my apartment and climb into my cousins overhead in the bathroom and watch me from the vent showering or bathing. Like he would be signaled from his army friends if I was in my bedroom so he could sneak in and out. (I heard things sometimes) One time I thought that he’d bugged my cat somehow to secretly listen or watch me in my apartment alone. Or he would talk into his watch to his army buddies in the barracks. (One time I was horny and tried to have sex with him and he said “Oh yeah, she wants it.” Weird right?) I would think that him and his army buddies were so fascinated with spying on girls that they’d park across the street of my apartment and try to spy on me with binoculars or something trying to catch me naked or masturbating. Weird shit. I would think things like that but would never say anything, just thought them, and I was okay with it. Is that normal? The guy I met before him was an active duty army veteran, and I thought that they knew each other somehow and both tried to see who could fuck me first. I would think that him and his army friends shared a car and whenever one wanted to visit a girl or what not, and if they would fuck her they’d go back to the barracks tell each other about it. Why would I think these things? Now I’m secretly obsessed with him even though I know all of these things not to be true. And I even miss those days and times when I’d have those thoughts. They were the funnest and the sex was always new, spontaneous and exciting. Anyways... we’d tried the relationship thing and that’s when it all went downhill. We claimed we both loved each other but he never showed any real affection towards me. Only kisses and sex. We never cuddled, we never did cute things together. He was fucking other girls. And then my winter depression came along and I no longer lived in my fun apartment with my two female roommates. But he told me he loved me and wanted me in his life for a long time and that he would be there for me. I believed him, but he never was. I finally felt like I could be accepted for how I was, emotionally broken and all. But I’d kind of let myself go since I was depressed. I think I scared him away, I would get upset with him not calling me or texting me when he was busy with army things. But I’m depressed. And he’s strong. I wish he cared more. But maybe that’s just how guys in the army are. Or maybe it was all only meant to be one big fantasy? ):
