The last week he's promised me sex hasn't happend its always the same Exuse I'm tired... :( I'm so horny all the time I don't even wanna share a bed with him or be near him. I feel so empty I feel unloved and unwanted. I really don't know how I feel he had been Messaging other woman calling them 'my dirty girl' sending them photos etc he tried denying it. At 1st then told me the truth this isn't the 1st Time. Ever since we seem to be at each others throats bikkering I suffer with depression and anxiety etc. (Getting help with) I just don't know what to do I don't know how I feel anymore my family think hes lovely they don't know what he's done to me.

I'd never cheat but feelin like this makes me want to. But I know if I did he will leave me with no washing machine or fridge! As we moved in togther an its his! 😕
