Yes, absolutely.
I've been single in my life for significantly longer (in total) than I've been in a relationship.
I have had many years of patronising comments. I had my eldest DC in my mid 20s so I never got the whole when was I going to settle down, etc, but I did get loads of people telling me how 'lucky' I was a couple of years later to meet my Ex, when I already had a baby etc (bloody joke, I had my own house, good job, money in bank - he got to move in with me for free and continue to be as domestically incapable as when he'd lived with his mum....he was the lucky one!).
Friends always asked me why I didn't have a boyfriend, with utterly no shame about it. Stuff like -didn't I feel uni was a waste of time because I was single for 3 years? I was working in the City, why didn't I find myself a nice man?
Thing is if you DARE ever admit you're less than 100% happy with being single you get either the advice to get yourself out there (ha fucking ha) or told that actually being in a relationship is shit and you don't know how lucky you are.
Yes right. If being single is amazing, and so much better, why aren't they all dumping their husbands? 
When you're single your life becomes public property. I don't comment on how my married friends dress, how their husbands must be fed up they never put on any make up or wear anything other than the standard mummy uniform, yet when you're single people feel at liberty to tell you it's because of how you dress, or the make up you wear, or to comment on you generally.
Thing is, it doesn't stop when you're in a relationship though. I thought finally having met someone, and being together for 2 years, I was 'safe'. Except now it's the 'not married yet?' 'not getting a place together?' stuff. And so it goes on...
