Sam, Welcome.
Sounds like you have a wonderful opportunity!
First question, how old is she? If she’s younger (typical college age), she may already see you as a higher-status individual, since you’re in your 30’s and going back to school. That sort of thing is usually associated with someone furthering their career and their life… all good things!
The answer to that question will also play a roll in what pheromones some of us can suggest. Younger woman tend to be intimidated with a strong none signature, so being mindful of this can help avoid any ghosting.
Secondly, what type of person are You? Outgoing? Social? Introvert? Extrovert? Pheromones can’t make the man, but they can and Do Help the man. If you’re the type to keep quiet and fly under the radar, then bathing in mones may not help much. The trick is to make sure your behavior is congruent with the mone signature you’re trying to portray. Clear as mud?
Here are a few products I suggest you search for and read up on. They’re all consumer line products, which means they’ve been tested for years, and deemed consistent enough for everyone’s use.
AMMO, AMMO world edition, AMMO summer edition. I’m not sure about world, but summer edition has a couple added ingredients to give it a more social vibe. AMMO is arguably the best stand-alone spray available; combining attraction and social.
Instant Honesty (IH). It is a communication oriented product that makes people feel as if they’ve known you a long time, and encourages them to tell you the truth… makes them feel like they can be themselves around you. Might play well considering she’s seems to be somewhat of a mystery right now.
a314. Arguably the most complex pheromone available. This comes in to-go spray bottles, or as an oil. This is a high-status and respect mone. Very Alpha type signature. Typically useful in a business setting, it also has it’s place in an attraction mix, provided you have a social or sexual mone to steer it with.
Instant Gentlemen (IG). If a314 is James Bond internationally recognized bad-ass and sexy, then IG is the warm, charismatic Sean Connery who-won’t-leave-you-in-the-morning guy. Some say it’s more subtle and more versatile than a314, since it’s more social and won’t need as much (or any) steering.
So read, read, read, and Then ask some questions. The search tool is your Friend! Browse each forum and read all of the Stickies, they were stickied for a reason. There’s tons of info on the forum, and dozens of very very helpful and knowledgable users that’ve been doing this for years. In the meantime, continue socializing with her and be observant!
Good luck, have fun
