My relationship is just not working out. The whole thing is a farce. We dont like together and everything we do is separate including holidays, christmas, days out etc. We basically see each other once a fortnight. That's it. There are tons of problems including his inability to handle money, his wierd obsession with being in competition with me (for instance I bought a new rug for my living room so he went out and bought a new rug for his living room. I booked a holiday so he immediately went out and booked a holiday that he couldn't really afford at the expense of paying off his credit card after already been bankrupt once).
But it's just not a happy relationship anyway. He ignores me when I speak to him (like a few days ago he'd come with me for a hospital appointment, when we came out I was telling him what the nurse said:
"So she said the problem isn't with my stomach, which leaves my ovaries unfortunately"
him - "oo coffee slice!"
"what??"
"umm coconut bars"
We were passing a starbucks counter - how silly of me to think I would be heard under these circumstances 
He lies which is also another major issue but the main thing is - he doesn't want the kids involved in our relationship at all so we can't "Progress" until the youngest leaves home. The youngest is 10!! So he thinks we can continue this ridiculous situation for another 10+ years?
Its just stupid, it isn't a relationship really at all and sooner or later one of us is going to find someone we CAN have a real relationship with and I don't think either of us would think twice of going for it. So why carry this on?
However everytime I tell him I'm not happy he panics and acts all mortified and insists that things ARE working
Therefore I'm wondering if I should just send him an email, explaining more or less what I've said here.
Or is that really bad of me?
