lust or love i cant tell

still in therapy it is definetly helping, going two times a week this is something she feels is nessasary. but i dont have a problem with that. she is very attractive, and from the first time i saw her i was in lust, she is 8 yrs older than me but doesnt look it nice legs, thats my favorite part, and yesterday she had a short shirt on nothing slutty very profesional looking but drove me nuts just the same. now here lies a bit of a problem i think i am falling in love with her all i can do is think about her and i cant wait for my next appt. so i can see her again. i dont know what to do should i tell her, maybe this is normal for a pacent to feel this way when someone is helping them then again she might think that she should stop seeing me then what would i do. i have thought that maybe it was the skirt and it was just tipical male reaction to seeing her but she did where a similar skirt a few weeks ago and it didn"t have the same affect. i cant wait to see her again, i love her!
