Feel Like A POS Girlfriend,

So I'm thirteen weeks pregnant today; and I swear every little thing my boyfriend does, drives me up the wall. He tries to kiss me and love on me all the time and even when I tell him I don't feel good and to kinda back up he keeps doing it and it drives me freaking crazy. One top of that he doesn't have perfect hygiene and his breath makes me sick to my stomach but I don't want to be like "Hey you smell gross brush your teeth" I just feel like such a shitty person for feeling this way... 😞 any advice??
