I'm just curious why is that so if any of you maybe have any experiences with this? I don't know whether it's boyfriend or not, but they might be a couple, they may night.
So basically I found out that there might be something going on between her and one guy for about one month now but she never says it's her boyfriend. She keeps telling everyone it's her friend but I saw them cuddle and share some kisses once so what do you think is the reason? I also talked to her once and she told me she got some business to do later but I saw her with him then.. also bare in mind that this guy was never at her house neither does he know her parents or friends. I asked her one day what she is doing and she said she's playing chess with a boyfriend and I said oohh is it him and she said it's not him lol.. a pretty stupid lie. She is also on one dating site and my friend started writing to her because I asked him if he could and she was so damn flirty.. okay, I don't want to hear what she is like, just answer the basic question please

)
my bet is on one of these..
1. She likes me or someone else more than him but is having him just to have someone beside her (she does call me, talks to me and acts somehow flirty)
2. They are just having fun, nothing serious, some sort of friends with benefits relationship
3. She doesn't want others to know.. but that would be just a stupid thing to do for so long.
Your opinion?
Thanks!
