Bf being sketchy?

My bf started his first day of work today and he Ubered up there and told me he’d Uber home . When I got home 5 min after him he was eating candy and drinking a modelo so I’m like the Uber made a stop at the gas station? And he’s like no my manager took me there on the way home ....yet he literally had txt me Uber dropped him off ....I’m like ok?? So so an hour later we went to HEB to grocery shop and when We got there he’s like go shop I need to grab something real quick and I’m like ima come with . But he literally sped walked past some people and isle and I lost him cuz I had a basket and I was stuck . I finally caught up to him and I ask him what he was looking for and he says condoms I’m like we just bought a 3 pack 4 days ago and used one . And he’s like that’s besides the point and I’m like ok??? So he’s like forget it and we shop and when I’m standing in line he dips off AGAIN and actually finds them. He buys them . And when we get home I’m like how many condoms do we have now and he’s like just 3 I can’t find the other pack and that’s why he bought a new pack . (Mind you we don’t have sex like that because I don’t have a high sex drive like him so idk what randomly made him want to buy condoms ) but whatever right so I go along with it .

Side note : The first 3 months of us being together he cheated on me with a girl he worked with and they would carpool to work but I didn’t find out till way way later After we had both relocated. We had just moved in and got new jobs . She randomly txt him saying she missed him he tried to say he ain’t know who she was I had him call her blah blah . It’s been a year since and tbh things have gotten way better . Although he hasn’t had a real job in 6 months But always came up with money somehow to help pay the bills and I didn’t ask any questions

So my older sister is telling me he’s probably pretending he lost the pack so he can use the pack with 2 left on his manager or go back to his old ways because how on your first day are you THAT comfortable buying a beer in front of your manager and you’re a truck driver and she’s making sense although I don’t know the gender of his manager but I know the one he trained all day with today was a woman

WHAT DO YALL THINK ?

He could have actually lost the condoms and just replaced it for us . Or I could just stupid all over again. My sister says when he goes to work tomorrow Look for the missing box it can only be in our bedroom so if it’s not there he’s clearly used them and disposed of it . If it is there and doesn’t have 2 he’s cheating.

But I shouldn’t have to go thru all this. Somebody tell me I’m over thinking !!
