Sorry, this ended up being quite long.
I've had several short- and medium-term relationships (which have all ended when one or both of us has fallen out of love with the other) but have never been in a longer-term relationship or married, and don't want to have children. I'm in my thirties and I've been single for several years now. I would like to get into a new relationship, but I'm not sure if it's fair on a potential partner. Since my last relationship, I've been diagnosed as autistic (something I'd suspected for a while) and it's given me a lot of insight into my behaviour and reactions, but has also made me realise that trying to get used to situations that make me uncomfortable is pointless (like how I hate going out to certain kinds of places, or certain kinds of unexpected plans). I used to force myself out of my comfort zone, but it never got any easier, and now I know why that is I just refuse instead and am a lot happier. To a certain extent, knowing has also helped me control my reactions - I have a point beyond which I can't, but there's definitely a bit more leeway where I can tell myself "this is getting to you so much because of the autism, try to stay calm" instead of just getting upset instantly. So far, so positive.
However. I've read a lot of articles and threads online about NT people's difficulties in relationships with people with autism (including the long-running support threads on here which have been so useful to read), and I think in a lot of ways that I will never be able to be a good long-term partner. I will never enjoy or be willing to do lots of the things that people talk about as a normal part of life (most holidays, many situations involving crowds or unfamiliar food that I don't feel is safe, regular big family gatherings, or living in a noisy, rambunctious household), and I can see myself becoming one of those partners who makes the other one feel like they're boxed in, if they like carefree travel for example. Obviously I don't want to do that to someone, and I take it on board when people wonder why their autistic partner sought out a relationship in the first place when their worldview is so inflexible.
Do you think it would be better for me to stay single? I am generally happy, and like I said I don't want children so there's no imperative for me to get into a relationship beyond simply wanting to. My good points in relationships are that I'm straightforward and loyal, I'm affectionate physically (and try my best verbally), I'm not possessive or jealous about my partner's time, friendships, hobbies, etc. (and expect the same in return), and I try my hardest to enter into my partner's interests (if they want). I would not make them feel like they were unappreciated or just there to fill a person-shaped space (which I've read about happening in autistic/NT relationships). My bad points are that I can be inflexible about certain things (like if we're meant to be leaving at a certain time), will sometimes get very upset when these things are breached even if I know it's unreasonable, I'm very bad at hiding my emotions to "keep the peace", I will never enjoy certain activities (e.g. most outdoor activities that involve getting dirty or camping or lots of sunlight, although as I said, I'd be perfectly happy for them to do stuff without me), and sometimes I think I'm having an objective discussion with someone about a topic but am actually coming across as argumentative (working on this). When I was younger I used to pretend to be "normal" in relationships and go along with whatever my partner wanted (until I'd break down "out of nowhere" and seem completely unreasonable) but it took such a toll and I find I'm less and less able/willing to these days, especially now I know it won't magically work to make me think/react "normally" if I keep doing it.
Of course there's always the option of finding someone else on the spectrum to date, but I don't know if I'd actively seek that out, as unless their areas of inflexibility coincided with mine I feel like it would cause more problems than it would solve. I could lie here and say I'd understand more, which I guess I would on an objective level, but to be completely honest I'd find it hard to empathise if I thought they were irrational and restrictive on my life (which I know is TOTALLY hypocritical, unreasonable and horrible, but there's no point lying when I'm asking for advice). Also, I prefer to be with someone less socially awkward and more at ease with the world than I am, rather than someone who's also anxious and rigid.
Please be honest here. I don't want to make someone unhappy, and I'm prepared to put in a lot of work to be as good a partner as possible, but I'll understand if people think I should stick to just having friends and not a romantic relationship.
