Was I out of line?

This guy saw my profile and it says im married. It says that cause it keeps the 'horndogs' away. I do have a boyfriend but im not married. He wrote me saying he didnt want to email anymore cause he thought I was married. i told him I wasnt then he said
" its ok...i am not a fool. But i wish you luck anyway....
it was nice to meet you.
thanks for your points! enjoy every single minute of your life!"
Then I said
" lame. Im not a liar, i have nothing to hide. I do have a Boyfriend but im not married. if you dont want to have friend for that reason fine......"
then he wrote
" lame? anyway....whatever i said, i didnt meant...
maybe you have got it wrong.....
i am not a person who insults anybody....but ok; Ashley...bye to you "

I try to write back telling him I was not calling him lame, just the situation but he blocked me, he was offended. I feel he was the one who was offensive by calling me a liar.
What do you think?

There was nothing sexual said. We were exchanging questions about the countries we live in. Then we were explaining ourselvs..

no....forget about him he was prolly drunk...or he was married himself looking for a no strings attatched relationship. blah he is just a jerk and trying to play a head game to see if you respond....obviously you did but he was just an internet friend right? there are millions of more good friends to be made.....uh...how is the weather in Cali?

It wasn't offensive calling you a liar, since you admit that you did lie on your profile (set yourself as married. ) He was not very understanding of the very realistic reason that you did that - but that's not out of the range of reasonable. IMHO, anyway.

Why does it bother you so much?

Blah Blah Blah.

Does it really truely matter? I mean if this guy never emails you again are you going to be heartbroken 5 yrs from now? But a lot of people put married on their profile and then say they arent to try to hook up with people so i can see his point. And vice versa a lot of people put single when they are truely married. But seriously not trying to be rude if you have a bf does it really matter if this guy never wants to email you agian.

Well... obviously, this person had different expectations than you had from your contact.
Otherwise, it would've made no sense whatsoover to quit contact with you in the first place.

You are dealing with an obvious sender-receiver horizon problem. You and he were talking and meaning different things than what the other understood.
His first answer indicates that wether you're married or just have a boyfriend, he's not a fool to think that the relationship (if you can call it that way) can go any further and that's why he quits.
You're not reacting to what he's implying (that he wanted to have a deeper relationship with you), but go on about a pen pal level of friendship.
At which point he thought he had insulted you about something, but he's not quite sure about what you were insulted.

That he blocks communication now most likely just means he doesn't want to waste time on a relationship that has no chance on going sexual.
Perhaps he got you wrong on some easy wording in your email communication that would have indicated that you are... open for more. It's very well possible if English isn't your native language.

But honestly, don't worry about it. He'll survive and so will you. And unless you have other stakes in this (like, he promised to be your tour guide when you are visiting Hamburg next week), well... Just let it go. It's not like your reputation will take permanent damage.
