My boyfriend has zero trust in me

So my boyfriend doesn’t trust me what so ever he keeps making fake profiles on social media and messaging me seeing i i will reply or if I will send pics to them or he will get his friends to add me who I haven’t met and to talk to me. There was this one guy who popped up to me and told me a joke so I was like okay this guys kinda funny I’ll talk to him so we was talking for months just as friends like asking how was school and stuff like that and one day I said I was going to go shopping but couldn’t be bothered waiting for the bus so he offered me a ride so I agreed. But when he came and I got in the car my boyfriend was waiting in the car for me turned out they had been planning it together and trying to see if I would cheat and basically playing me for months. But I had zero interest in this guy I just excepted a ride?? My boyfriend was calling me every name under the sun like a slut and a cheat while his friend just sat there really awkwardly. Was I wrong for talking to him and excepting a ride?
