I have neighbours who live 2 doors down who are a retired couple. She is disabled and he is her carer. We live either side of a corner house and the ends of our garden meet each other (this is relevant). We get on well. I think he is lonely although they do have family to visit. I've had them round for a few times for lunch or a cup of tea. When i go away he feeds my cats. I gave him my phone number in case his wife needs help when he is out.
Only now he is becoming increasingly over friendly. He climbs over the fence and does my gardening without me asking, and buys things for my kids practically every other day. I work full time but sometimes I bring work home to do in the afternoon. Every time he sees my car on the drive he phones and invites me round for a cup of tea, and when I decline next time I see him he says "I thought you'd fallen out with me" He just doesn't seem to understand that I'm not available! They are nice people but it's smothering me! Help!
