He's sent her more messages - after last time

[SoFreakingPissed]

Last time DP and I had a big bust up he started messaging women from work on Facebook. One inparticular was a young Thai girl. Nothing incriminating but definately making it obvious he liked her. When he thought we were going to break up permanantly he admitted to me that he did actually like this woman more than friends. But when we got back together we agreed he wouldn't message her anymore and just see her at work and as far as I know he stuck to this.
Well we had a bust up this morning and the stupid twat left his facebook on tonight in his office, I went on it and he messaged her tonight for the first time in ages - starting off with a joke, a wink, a x and then 'joking' about her cooking him a 'nice thai meal one time'.

Again, nothing too incriminating and at this point he could argue that they are just friends having a laugh but I am pissed off. Am I over-reacting because he hasn't actually "done anything wrong"? I don't know about anyone else but I know I certainly wouldn't private message a guy from work with winks and kisses and jokes about dinner.

Dearie me, not only is he disrespecting you but he is disrespecting her too. Cook him a nice thai meal?! He really thinks he's worth waiting on doesn't he?

You asked him not to message her anymore after their relationship had crossed into inappropriate and was making you uncomfortable- he then messages her behind your back anyway.
Yep, I'd be pretty pissed too OP.
Does he know you've seen the messages?

He can't be that thick can he? Sounds like he is punishing you for having a bust up so deliberately left it open knowing it would hurt and upset you.

many ways of seeing this....punishing you, ignoring your request post bust up, wanting more with her or .....just really doesn't give fxxxx

Two ready meal for him and take yourself out.

Have you got dc?

He can't make it any clearer, can he?

It's time to dump the bellend and find a nice guy to take you out for a Thai meal.

Your DP sounds like an immature twat to me. Don't make the mistake (that I made) of assuming that because he's messaging OW then they will always take him up on his suggestions. Sometimes they might tell him to f' off. You always have that option too - to tell him to f' off. Don't need to take it...but it's there remember.

fgs, dump this piss-taking twat

will he go chatting up other women every time you have a cross word ?

what will he do if you have a proper row ? Accidentally poke his dick into the first available female simply to wind you up ?

it's not worth it...get rid of him and find a grown-up to have a relationship with

He is a test. He is either punishing you, looking for an excuse to shag her, or can't stand the thought of being alone so is trying to set a new woman I case your split.
Any of these reasons would be enough to tell him to pack his stuff. All these reasons show he isn't actually that bothered about how you feel. He is just bothered about himself.
I wouldn't tell him I had seen. I would wait until tonight, get some Thai food in and serve it for dinner telling him 'i thought you wanted a nice Thai meal?' then kick him out. But that's just me.

AF as usual is spot on with her comments
