I worried a lot about this. I’ve known someone for about a year now and we ended up dating not too long ago. Couple months. So okay it is quite a bit ago. ^_
Needed to gain a lot of trust to do this but actually I could tell he wasn’t going to harm me. My advice for everyone else, true you never know if someone is lying to you online but I think talking to people online is more safe than talking to people in person because they could have not a clue who you are and you can just stop talking to them.
