cheating? 😠 anyone does weed?

i just know that my husband is damn well cheating on me. there will be days hed dress up and fix his hair so nice, just to go pick up weed. he usually go once a mth, but sometimes, hed go 3x a mth, once a week. telling me that one day he drops off money to them, and another he goes pick up. he always take 3hrs, but i just found out the place he picks up is only 20mins away. we moved to a new place, which is an hr away from the cities. i was hospitalized from a car accident, he told me hes going to sleep at home. left at 2pm and said hed come back at 7pm. he did come at 7pm, he was dressed nicely, and his hair was done. told me he went to grab weed. he never dresses up or fixes his hair nicely. ive never seen him do this since when we were still dating, which was 5yrs ago. its like he was also meeting up w other women and is trying to impress them! he never lets me go w him to pick up, well there was one time i did go w him, he was dressed up too. but he dropped me off at the store before he went to grab it. the place was only 5mins away, but he took almost an hr. hes lying to me that the place is an hr drive away from our house, but its actually only 50mins. and he always takes 3-4hrs just to go pick up. i just know it that hes cheating on me! one time he even changed his underwear before going! cause he didnt have time to shower and claims hes late. and didnt come home for 6hrs. now that we have a child together, he completely stop dressing up, and stop picking up weed at that place. he now buys weed from his bro in law. i feel like he was vheating and sleeping w other women the whole time, and decided to stop after we had our child!
