Anyone from north east England uk

Hi I've used a number of dating sites in the past as my lifestyle can be hectic at times and i don't get the chance to meet people in the normal manner of pubs and clubs as its just not my thing at all. Ive met a few people in the past some ok some made a friend and some turned out to be a mistake. Like most I've been lied to and cheated on and hurt .the thing is with sites there is deception. How do we know if the other person is actually telling the truth ? Lies from age to there relationship status. Why can people just not be honest about there situation and what they seek
