I have been seeing this girl for around 3 months now from work (i know dont shit where you eat. too late for that) and the sex is good she never turns me down for dates/meets or anything like that, its just that every now and then she kind of acts a little uninterested/cold with me like for instance just few word texts going nowhere for a few days.

When she does this on occasions it makes me go wild thinking about her to the point i cant sleep and get severe oneitis then eventually she will get keen again and i will be back to normal.

Any suggestions to stop this happening or why she does this because its literally killing me?
