Sometimes, it doesn't require a genius to figure out what's happening.
"I wanna get closer to you" - I didn't coerce or force you to say that. So, what made you say it? When you keep repeating over several conversations that you wanna get closer to me, and I asked you what you meant, you said you wanted to have sex with me. You wanted people to get close to you, so you have to use seduction to do it?
"The girls said you look good in what you're wearing today". - Oh really? They said so to you? Strange, why would they tell you that and not tell me directly? Perhaps it is you, who have that opinion, and dare not say it?
"He went around to tell others that a woman is infatuated with him." - And why would he do that if he didn't get any signals from you? And based on what I've observed, you seem to have given the same signals to a few persons, including me.
"I told him I try not to stray" - And why would he ask you that? Are you giving him any signals?
"I didn't tell anyone else, may be it is coincidence lah" - Very coincident that two IP addresses visited the same site at nearly the same time?
Stop doing it. Some day, you'll realize the consequences and the danger you're putting yourself in.
