My wife has left me 6 weeks ago, now she doing all the things we did together with the bloke she left me for,why??

Maybe you should have done those things over again with her to make her happy. Now are you going to develop a strategy to win her back ?

Tick

She is doing the things because she likes to do them most likely

Well, she has to do them with someone doesn't she? Sounds like she's jumped into another relationship really quickly and that this is really bothering you. What led to the break up?

Can you tell us WHY she left?

Did she just cheat and leave? Or did this develop over time?
