Meanwhile, I think it’s very hard to be the partner of someone with MS. Probably as bad as to be the one with MS. Clearly, she has changed towards you, that’s probably the result of the changes in you and your altered relationship as a result of the MS.
It’s a crappy situation for all of us who need our partners to be carers as well as husbands and wives. There are times when my husband gets a bit tetchy because I’m asking for help quite a lot of the time. I try to understand his feelings and I think he tries to understand mine. But it’s not easy to retain exactly the relationship you had before MS moved in and took over your lives.
Having said that, if your wife is getting angry and walking out, leaving you alone for hours, that’s a completely different thing. Have you tried talking about your altered relationship with her? Perhaps at a time when you’re both in a good mood and you’ve not had to ask for help for a while.
Alternatively, I don’t know your situation or care needs, but if you require more in the way of personal care, is it possible to have a social services care assessment? You might find that you could be getting some help with personal care from a third party rather than just relying on your wife. Or of course, apply for PIP and maybe having some extra money might enable you to either get more aids and adaptations to help, so you’re not quite so dependent on your wife, or can pay for some personal care?
I do hope you find a way to resolve the difficulties with your relationship, if she understood how you’re feeling about her change towards you, it might make a difference in that behaviour.
