Likes are easy. I didn't mind getting a like from a woman, but I wasn't big on going around and just liking women. If I was interested I sent a message that would be engaging based on her profile. Attractive women can get overwhelmed with emails (more so with likes) so a guy needs to put forth a good effort or he gets lost amongst all the other messages. I've had women Like me and then I've messaged them if I was interested, usually only about 10% of the time and then heard nothing back. My previous girlfriend that happened with. I waited a few days after not hearing back and messaged her again and we ended up talking that night and were together about a year. 2 messages tops without hearing anything back then I'm done. It does happen after a first non response, just give yourself the 2 message max.
