<human>: I have only been in one relationship ever and that is only the case because my ex-girlfriend was very forward and told me that she was interested in going on a date. When I am interested in a girl I usually think they are just being friendly while talking. Typically in person girls that I am interested in(usually girls I have known for a while but I wouldn't consider a friend) engage me as often as I engage them, but over text or facebook I almost always send the first message, then I feel like I am carrying the conversation so I stop talking to them after a few conversations. 

I consider myself to be below average looking, and maybe my self-esteem convinces me that no one would be romantically interested in me.

Can you provide a brief overview of the text?
<bot>: Low self-esteem. How do I tell if a girl likes me, or is only talking to me as a friend or to be friendly?
