This has got to be a troll thread... if not man you need serious mental help. Who gets enjoyment from seeing someone you know suffer?
I hope you meet or have met someone you love.
Firstly, the OP has not given his/her sex out - it's fair to assume he is male, but he might be speaking from a lesbian POV.
(Slipping in to describe him as male, just based on his posting)
Secondly, you must be naive if your thinking the relationships the OP has been in has been for a lengthy period (I'd most likely put the medium as say, 4 months) Because the intermeshing of a relationship your considering would be years - not months.
Some people may react in a... rash way like described - but in short term relationships, i'd imagine you slightly incapable of handling rejection.
This doesn't lessen his dickery, merely putting it in comparison.
How would you feel if you were the by product of someone doing this to you own Mother? Still think it would be cool?
No but you destroy someone on the inside.
Someone who loves you as a person, Loves you physically and makes you the center of their world. Their heart gets weak and they get a butterfly feeling in their stomachs when they see you, When their heart flutters when they tell you they love you.
When you cheat? You destroy that person and they are filled with nothing but grief and sorrow.
It's like being stabbed in the heart, You enjoy destroying people on the inside? Who they are as a person? Making them a broken husk, Unable and scared to try and find love again?
Fuck you
When you see someone in a thread making the same canned responses over and over, click their name, click view forum posts, and see if they are a troll. Then don't feed them."Gamer" is not a bad word. I identify as a gamer. When calling out those who persecute and harass, the word you're looking for is "asshole." @_DonAdams
I'm no psychologist and neither are any of these people here, but this behaviour is not normal or natural, and you can tell yourself that you can't help it and that it's not a problem all you like, fact remains it IS a problem. Both for you on the long term, as well as for the people you hurt with it.
Of course you're not a murderer. Of course there's worse things out there than your 'addiction' to cheat on someone. That doesn't however excuse what you're doing, or excuse not finding help. Talk to a psychologist, even if it's just once. As I see it, you can only gain by it by doing that. You wouldn't have posted here if you were really okay with how you are.
