Hello lovely, it's OK to get steaming drunk and feel a bit sad, FFS have a damn good wallow if you want to, I'm damn sure I would in your shoes.
If you're still reading, and don't feel like posting any more, we don't mind. Do whatever you have to do to feel safe, sane and able to cope.
Long ago in my early twenties I was sharing a flat with a friend and we had a very good rule when we split up with a boyfriend / were horribly dumped or similar. We had two weeks in which to completely wallow, get drunk, talk about them all the time and feel really hard done by and sorry for ourselves. By the end of the two weeks you were so sick to death of it that you felt ready to get on with your life and forget all about them.
Now I know you can't realistically do that, and you deserve more than two weeks because this is a marriage you're mourning, not just a boyfriend of a couple of months, but the advice remains the same. Let yourself feel the sadness and the unfairness of it all and feel really, really sorry for yourself for a while. Soon you'll get out the other side and feel lighter again. It's one of those things you can't avoid, sooner or later you have to feel it, and getting drunk is often a really good thing to do because it makes you feel maudlin and cross and then you can let it all out.
If you've had enough of posting about it, we totally understand, and wish you a happier future, with so much love and support.
