First orchid, department store

I realize I could do so much research but I really just want it straight from an orchid lover. This is my first orchid. I have several houseplants, but I have never had an orchid, or any flowering houseplants for that matter. I’ve never gotten one for myself because I am intimidated by them. I got one for Valentine’s Day and it is so gorgeous. Blooms just keep popping open and I’m in love. I want to take care of her, and keep her forever. I don’t know much about orchids in general. I understand they don’t like direct light. It’s from the store of course and is in the clear pot with the wet moss. I’ve not watered it, I’ve not done anything with it but move it to brighter places when the sun comes up in the morning. I keep wanting to move it to a chunkier and dryer mix but it seems to be doing amazing in the wet moss. It seems almost each time I look at it it’s popped open another bloom. Please give me any and all tips you could offer. When SHOULD I transplant? How much light does she need each day? Watering schedules? Appropriate time for transplanting? How can I take care of the stems so I don’t end up with just the leaves For-EVER like so many I’ve seen? Feeding her, fertilizing etc. please tell me everything from your experience with keeping a department-store bought orchid alive and thriving. Please. :)
