DP and I have been together 3.5 years without a single argument. Recently some things he does/says have been annoying me but they're reasonably small so not sure if they're really worthy of being the first argument!
Examples: he saya: "I'm glad I could help you out" if he has our 8 month old DD for a little bit on his days off while I work on my degree.
He speaks to 5 year old DD in a simple/improper way, I.e. "today I did go to the shop" rather than I went.
He is inconsistent with elder DD - one day he'll tell her to shut the door of a room after she enters it, the next day when she does so he'll tell her off for playing with doors!
DD1 would like 15 mins of having me to herself to read to me/me to her at bedtime as I have DD2 the rest of the time. DD2 will only settle with him if she can't see me but despite him knowing this he stays where she can see me so I end up taking her and juggling both kids.
He keeps saying he can't wait til DD2 goes in her own room and sleeps all night so we can have more sex, but he doesn't see getting her to that milestone as his responsibility, he thinks it's all up to me as I BF.
AIBU to raise any/all these issues and start our first ever disagreement?
