Hi since you haven't done magic before and what something specific I don't want to discourage you. You should try spells which attract luck and good things in general to your life.
Lets say if you get him back, you'll be stuck in a relationship with someone unreliable and bad with money. I don't know your person, so let's just assume that.
With a spell to improve your life conditions you may find yourself:
Getting a job interview on an impulse that recoops your lost money and let's you get more money in the future
Finding a guy who makes you happy and who your compatible with
The best magic is kind of vague in my opinion. Not because it doesn't address specific concerns (like love, money, etc), but because it lets the universe or whatever god or force you employ to decide the best outcome
If you want some ideas on specific spells, ask for me by name on this forum or send me a message
