<human>: Give me a shortened version of the text

Hi everyone,

My girlfriend and I are looking for advice on how to break up with some friends, a couple (we will call them Don and Debbie) who are very persistent, bordering on clingy.

This situation started because Don moved to our city last year. Our mutual friend asked to give Don my contact information, and I was fine with it. I had moved to the city a couple years ago, and understood the struggle of moving somewhere where you don't know anybody. Other than our mutual friend, we have no connection to Don and Debbie. 

So Don moves here, he is busy getting settled, busy with work, etc.  My girlfriend and I hang out with him a few times, and it's fine. We don't have a lot in common, but are fine with grabbing an occasional beer with him.

Then my girlfriend and I buy a house about an hour from the city, my girlfriend starts a new job which requires a lot of travel, and our time becomes very limited. This is also when Don's girlfriend, Debbie, 
moves to join him in the city. After Debbie moves up here, they start asking to hang out a couple times a week. At first, we politely decline, saying how busy we are with the new house, new job, etc. However, they have only gotten more persistent. They will often both message us over and over and over again until we respond. If we don't reply to Debbie's texts immediately, she will message us over facebook. When we do hang out with them, they try to make us feel guilty for not hanging out with them more. It's gotten to the point where we are tired of having to constantly explain to them that we have a lot going on right now. 

They aren't bad people by any means. It just seems like we are the only people they know here. However, we don't have a lot in common with them, we live relatively far from them, and they won't back off. We've decided we need to end the friendship. How do we do this? I'm ready to ghost them, and block them on social media, but my girlfriend thinks we should give them an explanation. What do we tell them?
<bot>: Friends are too clingy. Girlfriend and I want to end the friendship. How do we explain that we don't want to be friends?
