Name changed for this one to be on the safe side.
My live-in DP has a friend, let's call him Dave, who has been texting him most days during lockdown, at what seems like an increasing rate. He was texting before lockdown, but it has become more noticeable (for DP and myself) during lockdown. A few months ago they would have a bit of banter and talk about the novelty of lockdown, but now Dave is sending very similar opening texts every day or every other day. DP is getting a bit tired of it, to the point I am beginning to become irritated as well.
DP sometimes takes ages to reply and has tried talking about things he knows Dave has little interest in, but that doesn't seem to make any difference.
AIBU to think Dave is a bit overbearing, and do you have any tips for reducing the frequency of texts without being brutally blunt?
