I’m afraid I don’t really have any useful advice. However, let me assure you you’re not the only one stuck in this difficult position of not being quite chareidi and not quite MO.
As for me, my wife is strictly chareidi and I myself am more MOish. When we got married I was more of the chassidishe BT type – but it’s just not my thing. I’m more comfortable/stable like this. But it does put me also in this impossible situation, which is very difficult in Gateshead in particular.
