This is a bad idea on multiple levels. I strongly advise against it.
First, basic psychology: it’s too impatient, putting the cart before the horse.
Women think differently. They are attracted to those they love. If they don’t like you they won’t be interested generally, so fix that first. You want her to fall back in love with you. The counselling will do more for this than anything.
Second, love magick interferes with free will and is basically a psychic attack, and very baneful.
Love and lust are very complex and affect us at many layers of our beings. Magick tends to be short signed due to the underlying intent, so it affects parts and not others, and this can send the target insane by causing conflicts they don’t understand. Sometimes they become obsessed and aggressive towards you, most of the time it makes them sense you as an attacker and run away. You can search for the stories here on he forum: love spells on exes usually fail at best or make things worse. Open attraction spells for a new love that is perfect for you work the best.
You have bigger problems than getting sex from her, and it’s also too much too soon, especially as you’re new to this and don’t have the senses to see the energy and adapt if it goes sideways.
But before you get into heavier magick like this, please, please learn to banish and cleanse to maintain your 'spiritual hygiene". Doing magick attracts interest from the other side, and some of it isn’t nice. We call them parasites, some call them demons, and we set up shields and wards to prevent them, like fencing your yard. Then if you get a nasty you know how to get rid of it.
You are already attracting parasites that see your stress and find that yummy to feed on. And you will look even more attractive when you start doing more magick. You don’t want to make a problem for yourself that you don’t know how to get out of.
After that, if you still want to try it then for romantic attraction and lust I’d go with Amon.
I’d use Corwin Hargrove’s Goetia Pathworking book and use that technique to contact Amon. He can reconcile the friendship and then stimulate romantic feelings, and from there the lust.
