In my experience good therapy will be painful, but maybe she is just moving too fast right now, in which case you could try asking her to slow down? I think the relationship will change and how you experience therapy will change as time goes on. Communication and connection are the key ingredients though. I don't personally think love is destructive, obsession might be, but love is not obsession, not to say both can't exist. Just remember obsession festers in the dark and in secrecy. Hence, you need to be able to communicate openly with your therapist about all that you feel for therapy to be most effective.

Therapists do compliment in my experience, but they don't throw compliments around on a whim. I'd say they are less complimentary than friends or acquaintances because they try to only say genuine and authentic things. In my experience it might take some time before you hear what they like about you... Because they will wait until it is hopefully a sure thing correct compliment. I.e. my therapist didn't start off telling me I was a nice person until I had a long track record of niceness.
