Out of the blue just now, I have had an ex client (or more so TW) contact me on my work phone.

When my ex set up an AW profile for me and pimped me for a few months (then I grew stronger and told him to do one), this was one of the guys who contacted me on the AW profile (years ago). We got a little PAYG cheap phone, with no blocking facilities so it was a case of ignoring the TW's.

This guy made a booking then said he couldn't go through with it. So we put him down as a TW.

Now, years later, he's contacted me again on my work phone out the blue, saying he's got feelings for me. I told him simply. Make a booking, e.g. with me (as my AW profile no longer exists) or skedattle. Now all I'm getting is how he misses me etc.

I seriously don't know what to do. Tried ignoring, but the texts are still beeping, even though I put him back as "Mark- the Pretty Woman Timewaster" on my phone.

Lil L, you can get a phone from carphonewarehouse for less than a fiver that has the blocking facility and keep your same number.  It may be the best fiver you ever spent.
