Can I really trust this new work friendship after past betrayal?

I do talk to coworkers at work but not like eat lunch together or panning on hanging out side of work for a while I realized there isn’t any real friends and I mainly talking about same gender friends as a woman I once was a friend with this girl I had to train her and all and I realized she was jealous of me and talked falsely about me so I kinda lost trust in friends especially work until this new Philippine girl came along and somehow we just randomly got along and we literally tell each other everything I mean work wise and she offered to hang outside of work but it hasn’t happened yet bc it either don’t work for me or her that day but yea we eat lunch together gossip together laugh together and I can go on.. is there really a true friend at work?

Can I really trust this new work friendship after past betrayal?
