The advocate of personal freedom is dedicated to:

So women are needed exclusively for sex and talk. And every new girlfriend is warned about it. At first no problems. But for some reason, three months later, some incomprehensible claims begin and, of course, the girlfriend is sent a long way away. Well, I’m a bitch and cattle of course.)

I suppose the problem lies in "talk". If we are talking about intellectual conversations with self-sufficient women (supporters of free relationships) - the option of "simply sex" is very realistic, if conversations are of the nature of emotional immersion in each other's life problems, I think this forms an atmosphere of too confident relationships (women count it as a signal to the next stage of your relationship).
My advice is to talk separately, sleep separately (with different women). And don’t play in the "double games". Are you looking forward to "easy relationships"? Then do not burden your partner with your experiences, etc. Otherwise, the result will always be the same.
