No I didn’t cheat! Just having feelings

I have been married for a couple years and had a baby 8 months ago. I love my husband. I really do! We get along great, laugh together, enjoy each other company all that stuff. I had some dreams of an ex of mine who I also REALLY loved. We only broke up because my sister died and I spiraled into depression and cut him off completely with no warning. He was always there for me and made me feel so special. Ever since having these dreams he has been on my mind. When I think about my relationship with him vs my husband they are completely different. He was way more spunky and sexually compatible with me. We would have sex anywhere anytime. My husband denies me sometimes because he is too tired or “we just had sex yesterday” and it really makes me feel unloved. He is DEFINITELY not cheating on me so don’t even go there please. My ex also so me at my absolute worst when my sister died and took care of me for weeks after when I couldn’t even take care of myself. He showered me, fed me, literally picked me up off the ground when I physically couldn’t get up. My husband has never seen that sort of me and by not fault of his own he just wasn’t the man in my life at that time. Am I wrong to be missing what I had with my ex? The spontaneity and the sexual side along with the genuine affection and attention he gave me?’u husband takes care of my basic needs (bills and food) but the affection department isn’t his strong suit. I knew this when I married him I just didn’t know it would end up affecting me as much as it does. I have to ask and beg for his attention sometimes and it’s turnoff. Just looking for some advice and needed to vent.
