Argument rematch?! 🤷🏽‍♀️🙇🏽‍♀️

Ever have a argument with your SO and only after the argument do you remember or come up with what you NEEDED to say and how you should’ve said it?!? or you sit there and think of all the PERFECT examples you could’ve used to prove your sound logic?!? FML that’s me tonight... I hate confrontation but I’ve been learning to not let shit slide like I used to... I’m much more vocal about what I do and don’t like, What I’ll accept and won’t and of course.. Don’t get me wrong I don’t go on attack mode, cause a scene and it takes me a long time of pushing buttons to “get loud” but it’s caused some “tension” around here.. I’ve been living with him for 2 years now, we’ve had all the BIG convos.. babies, Marriage, religion, financial situation. All of it... we had guests the other day and they were talking about how they were trying to start a family and the topic of marriage came up... and MY man sat there and said he didn’t believe in marriage and wasn’t sure about kids! 👀 like since when?!?? Because it sure doesn’t match what said to me! The night was over and I brought it up to him.... and he said the same thing.. I asked what made him change his views and he said “I don’t think a piece of paper changes much” “that’s just another way for people to commercialize love” 😧🤭 I was really stuck! Didn’t even know what to say... and now I’m a little confused on how I feel... 2 years... and now this? Would I be crazy for ending the whole thing now and save myself from wasting more time in this relationship?
