Old date has contacted but am in LTR... how to reply?

[CouldBeBetterAlone]

I had 2 dates with this person, lots of emails, about 18 months ago. Slept together once.
He has made contact out of the blue. What do I reply?
I think brief one liner saying I am in a relationship. My friend says don’t reply... who is right?

What exactly did his message say?

Don’t reply

You are. Tell him you're in a committed relationship now and wish him well and then it's clear that he should leave you alone.

Thanks! Message just said “hi, remember me, how are you?” Quite sweet really but he was a bit pick-up-put-down whenever it suited him...

I’m with your friend. You don’t owe him anything. My opinion is that you would only really reply if you were hoping to start something up.
Delete, block, move on

I would ignore it and block his number. You don't owe anything.

This is not sweet at all. He’s newly single and sending the same message to all the women in his phone book. Avoid!

I wouldnt bother replying. Im sure he wont feel that hard done by being as he is just putting feelers out. If he does a follow up message, then reply. I dont even think it rude to ignore him in this context to be honest. He can read between the lines.

If perhaps you knew him well (from the emails you said you sent between and after dates etc) it can't hurt to say something in reply mentioning what you're up to, talk about partner and ask how they are. No need to be rude or anything as they've taken the time to pop you a message. If they're only interested in rekindling something then at least they know you're unavailable. I don't know if it's about owing anyone anything but just maybe being polite.

Then why do you feel you owe him any consideration? He's clearly between shags and testing the water.

Ha! Yes I did wonder if feelers were out! Ok yes, will ignore.

Why would you even want to reply?
Ignore & delete
His message isn’t sweet.

Sweet? He's after a shag OP.

He’s just trying to pick you up and put you down again! Sounds like he hasn’t changed.

Eh? Just ignore.

Ok thanks everyone!
