AIBU to think that my boyfriends friend is up to no good.

[Shootfirstaskquestionslater]

My boyfriend has this friend that he only ever sees when his friend knows he's got his money my boyfirend thinks this friend is just helping him out because my boyfriend has anixety and depression and never goes out anywhere this friend goes to all the medicals with him knows exactly how much money he gets and when he gets it my boyfriend just hands this friend his card so that he can do shopping for him. What made me think his friend was maybe up to no good was a couple of weeks ago they had a massive falling out because my boyfriend told this friend he would lend him money for a new phone but then he didn't have the money to help him out because he had been helping out another friend who needed a place to stay after his long term relationship broke down. My boyfriend was upset over this arguement but that was when I kind of thought hang on this friend only ever apparers when he knows he's got his money and he got pissed off that he didn't get money out of him for a new phone. This friend does his shopping for him and everything. Am I right to be worried that this friend could be up to no good or should I just keep my nose out and let them get on with it. I think I'm only supiscious because someone I thought I could trust robbed a load of money off me so maybe thats just clouding my judgement.

How could he be doing wrong? When he does the shopping does he provide a receipt and change?

I don't know if he does it's just the fact that he only ever turns up when he knows he's got money and arguing with my boyfriend because he couldn't lend him money for a phone it's not my boyfriend's responsibility to replace a phone that his friend broke.
