Hi October
Can I ask you, do you actually want things to work out with DH?
It's just that you seem 'stuck' at the moment. You don't seem to be moving forward in your relationship with him and reading your posts you just don't seem to like him very much.
I understand that you feel he doesn't treat you well and he is jealous and insecure when it comes to your work and your friends but could you not just rise above all that, continue to enjoy the things that bring you joy and make a defined attepmt at not letting DH's negativity drag you down.
Your depression seems to be hinged on DH, what he feels, thinks and says. Then added to that you have the 'colleague'.
I reckon its time to stop being a sponge, stop soaking up all the negativity that comes from these two blokes. Listen to us not them. Come on now! You can do it!! xx
