Should I be worried about our relationship?

It just seems that most of his friends have bad views on women...like his best friend emotionally cheated on his gf of 3 years and ended up dating a new girl. He’s been like talking to others girls on dating apps while he was in a relationship. And none of his friends are married so it makes me think my bf is a bad guy also bc he’s hanging around these influences.

Also my bf lost his job and he doesn’t tell me what he’s up to...
