ever since we have been together my fiance hates kissing me, and when we do kiss she shoves her tongue down my throat and its disgusting, plus there is no spark or any type of fireworks when we hug and kiss.
UGH sounds awful I would break up if I were you. If there's no spark there's really nothing you can do about it. Life is way too short to waste your time on someone who isn't right for you. Find someone who is just as excited by you as you are by them.
Do you guys even have sex? She might not be attracted to you physically. If that's so, you need to run away right now. She could be into you just for your money or some other hidden reason. A girl should love to kiss you and if doesn't, she might be using you or have some really deep emotional issues that prevent her getting closer to you. Honestly, you need to answer the questions above and update your question. This is a serious issue!
