Hi ! That's a tough one! It really revolves around how comfortable you are with discussing it. I have found that, as I've gotten older, it's been easier to discuss. Now that I'm in my 40s, more folks are used to hearing about some sort of major life change like that. At some point, everyone has something that feels weird to discuss. In my own personal case, I try to get it out of the way early (if it's going to be an issue, I want to know ASAP). I'm sure it's chased some folks off but I'm better off knowing that sooner than later (in some ways, disclosing something like MS is an advantage because it helps us waste less time with people that we wouldn't eventually mesh with anyway). I often approach it like "I used to be a software engineer but I had to leave that line of work because I have MS..." and then kind of go from there. Usually, they will ask questions and I'll go from there.
One more thing I'll point out, I've found that dating after being disabled with MS has gotten me more in touch with my own interests and expanded who I am. It's made me notice there is more to life than I used to think. Sometimes I feel bad for the folks I've met dating who can really only categorize themselves by their jobs or their children or other such accomplishments. There is a lot more to life than all that and I think people can get so busy they forget that. Your change in life because of MS can certainly be thought of as a negative, but there are certainly some positives in there too, do be afraid to acknowledge that. Most of us can't work anymore because we can't be consistent enough, not because we can't do things. That can be hard for others to understand, but be proud of your interests and the things that you do do and remember those are things you can talk about (and that will probably be much more interesting then them if they only talk about their careers).
Best of luck and sorry for rambling!
