Re: when will I stop thinking about her?
well I think you will be feeling this way for quite sometime. Both Mercury and Moon are peregrine here, wandering aimlessly and lost. It will be quite sometime before there is change. Moon will change signs into its own sign Cancer in 11 weeks from the time of question. Mercury is going into 8th house - still more worry and sadness to come. Your 5th ruler Saturn is also Rx, love and romance are not going anywhere for you, dissappointments in this area.
So I think 3 months, but most likley you will be feeling much better when Mercury enters Gemeni in realtime - thats about end of May. Emotionally things will be better in 3 months. You will feel much in control and positive.
