I share the exact same experience, thank you for putting it on paper in such a clear way. I had men want to sleep over, or inviting me to their house to "listen to music and read". I fell a few times too. And learned my lesson too. In my opinion, men need to be educated, or "trained". You must explain to them very clearly your rules. If they respect them and are willing to put in the effort to, fine. If not- goodbye.

Yes, I share the same feeling: it's sad, because "rules" and "boundaries" kill true love and affection and commitment and all the romantic feelings we long for...
