<human>: Can you condense the text into three sentences or less?

Last month, our friend Jon began housing Eric, who moved across the country, basically for the sole purpose of hanging out with our friend group. Jon and Eric met online on a forum, and have known each other for a year or two. I've also known Eric for six months or so, because we'd interacted on Twitter a few times.

My roommate, Wes and I aren't very fond Eric. He's okay, but not someone we'd want to see more than a few times a month, at the various events that happen in our community. Before Eric moved here, Jon came over and slept over at our place often and that was fine. We really enjoy Jon's company. The problem is, now that Eric lives with Jon, every time Jon comes over, Eric does as well, and every time Jon sleeps over, Eric also will.

Wes and I really don't feel comfortable when Eric's around, and he's around a lot. Wes will often just retreat to his room for the duration of Eric's visit. Now we've started to dread inviting Jon over, because even though we never mention Eric, he will always show up. We also feel like Jon might not like Eric all that much either, but is too nice of a guy to really say anything to him. Eric just kind of invites himself to everything Jon's a part of.

We understand Eric moved really far away to hang out with all of us, and so we're trying not to be mean to him or shun him, as he doesn't really have anywhere else to go. I also understand we need to talk to Jon, and tell him what our issues with Eric are.

What I'm looking for is advice on how we should tell Jon how we feel about Eric, and assuming Jon feels the same way as us, what we can advise Jon to do about the whole Eric situation.
<bot>: Our friend's roommate tags along with him everywhere he goes. We don't like his roommate very much. Looking for advice on what to tell our friend.
