Is my boyfriend’s friend into me or just overly attached and lonely?

My boyfriend and I have been together for the past several months. He has a friend (male) that happens to live 2 doors down from me, to which I had never known until my boyfriend introduced me to him after going over with boyfriend a few times, I'm very kept to myself person. He seemed to be an alright person until the one day he came over and started venting about his baby mama, how she wants to move on and started bringing up my boyfriend's past and making himself sound like he's "better" for example he told me my boyfriend had to go to anger management because it was court-ordered where as he said he took it at his own free will and just other things almost as though he's trying to make himself sound "better" than him plus he started texting, snapchatting, calling me on a daily basis (my boyfriend is kinda not good at answering his phone) and also applied to the same place I work, so I started keeping my distance from him and told my boyfriend about it to which my boyfriend told me to then tell his buddy to stop then, but I have not said anything, I've just made distance, such as not answering him at all, not going over there anymore with my boyfriend and he kind of backed off... then the other day he found out his baby mama cheated on him when they wete together (this was 2 years ago) but is now back to calling, texting, snapchating me again to which I keep ignoring his calls, texts, etc. I guess he was looking for a ride to the store (my boyfriend told me) I have not even opened them. I find this behavior to be odd and uncomfortable. It almost feels like he's trying to get between us, but my boyfriend said he's his only friend&texts him all the time too, which could be true, but in my opinion it's too much and it all seems weird especially that he applied for a job at the same place I work, but havr since quit as I got a different, better job. My gut just has a bad feeling. Does this friend have a thing for me or am I crazy?
