I would go along with it and hang out and don't expect anything more. At worst, you have a fun new friend whom you like to hang out with --that's a win! Since she has no problems making the first move, if she wants this to be more, she'll let you know. Just have fun with your new friend!
No. You cannot target areas to lean out. This also holds for exercise: doing sit-ups will not burn the fat off your abs. The fat will also not necessarily come off evenly. Sometimes it does, sometimes the saddlebags stay until the bitter end even when your ribs are clearly visible. Genetics does play a role, but it can be dealt with.
(I'm a trainer and physiologist and helping people to lose fat is something I do.)
