Are you sure that you’ve mastered positive thinking? I just question that because you’re not being honest about your living situation with someone whom you connect. Don’t be afraid to be honest about it – you may miss a great opportunity. That girl may not be around in a few months, and if she cares about you, then she won’t be turned off. I have friends who CHOOSE to be homeless – they say they have never felt so free. If I remember correctly, the Buddha also was homeless for a time. I would suggest being honest and open with her, rather than causing her pain by shielding yourself from possible embarrassment. (Not that you have nothing to be embarrassed about!!)

Namaste
