I can really relate to your questioning. I believe I met mine, and this was around the same time I started delving into astrology a lot more. The two weren't related, I just happened to get back into around that sane time.I did have that gut feeling, but I couldn't help but check it out astrologically.
I have learned while doing this many things. Astrology can delude you in good ways, and bad. What it can't do is ever give you a definitive answer. Yes I believe in astrology, but its also a very interpretive study just like any religion or philosophy. Even love for that matter. All you have is instinct and gut. Love is emotion (it goes beyond that, sure) but there is no exact science when it comes to human relationships.
However, are there things to look for astrologically when it comes to love? There is many! Transits will tell you when events are likely to take place.
Places to look might be ascendant transits (or aspects) descent transits (or aspects) what's going on in the 5th, 7th, (and sometimes, 9th house). Look at your fifth and 7th house rulers and if there are any transits to those. These might tell you when you will meet someone, but not necessarily if they're the love of your life. They may also be clues to engagements, weddings, children, break-ups or divorce. Transits to north node are great indicators too.
Aspects between eachothers planets (synastry) may indict what type of relationship you'll have and how powerful it is. To get you started look at the polar feminine and masculine aspects.
Ascendant can be interpreted as the self or the male while the descendant can be interpreted as others or the female.
The you have Venus and mars. Sun (man) and moon) woman. Saturn (woman) and Jupiter (male). Saturn may also indicate security or control, while Jupiter may indicate fortune or expansion. Uranus brings change and disruption, Neptune brings illusion, Pluto brings transformation.
Try cross examining the male and female planets. Do any of your male planets conjunct, trine or sextile his male or female planets. A male to male might conj for example might indicate that he is an ideal man for you. A female to female might indicate you as his ideal women. A male to woman is a stronger pairing that you two can work together as one and you both feel that bond.
The important thing is to learn and have fun but leave the decision making to your heart.
If you feel like he's the one, why not go with it? It's a great feeling
