You sound like you take a lot of risks with these men, online relationships can turn out dirty and useless, when the time comes to breakit off especially. Me myself wouldn't trust someone I met online, and you should find out as much as you can when dating these people, find out their past maybe through conversation, they sometimes know what to say to get someone, but when it comes down to it, they aren't what they told you, i'm just saying be very careful of who you meet online too.
