I come from China. I am thirty. [always spaces after full stops] I am single now. Yes, [spaces after commas as well] the girl like me that [acceptable, but should be 'who' instead of 'that') havent hasn't [We're talking about a singular action, here, so it is 'has not' not 'have not'. If you had said 'the girls like me' (plural) then you could use 'haven't'] married is old enough in China. So I [always capitalise 'I'] was [not sure if this is meant to be in the past tense or not?] called the girl remained. Of course, I am not a Bachelor. I just haven't (note that 'haven't' is equal to 'have not'. You mark the contraction with a '] found the other half of main me [I think that you meant 'mine' here, but spelt it correctly. However, if this is the case, then it should be 'me' instead]. .I beleive that I will find him in the future. Well, bless me, please.

Hi. I live in the UK, and here it is pretty common to be unmarried at that age. I am sure you will find someone. :)
