I (21f) am devastated about my (21m) fiance lying to me.

Weve been together for two years. Absolutely inseparable since day one and we compliment each other so well. I love him so so much. I noticed that he lied about taking my dog out and instead went out to ride his motorcycle. He also lied about going through my phone at night. Finally, he does these stupid jokes that really fuck with my head. Like “omg i got a ticket in your car” and id believe him and be upset then hed be like “haha just kidding” like constantly. All of this combined has me an absolute trainwreck and I cant stop crying over this. Am I being dramatic? It feels like the whole foundation of our relationship is shifted because he made a big deal of being so truthful to me.

Tl;dr: my fiance lies to me about simple things and messes with the trust between us and I feel like I am overreacting about being so tore up and sobbing about it
