I believe in true love but I don't believe in the concept that you only have one true love. From my experience, there are different aspects of love, such as physical attraction, chemistry, similar interests, having compatible personalities and of course friendship. Finding one or even a few of these is pretty easy but finding everything you are looking for in one person is what true love is but is definitely possible and can happen with multiple people.
At the risk of sounding cheesy, it's not about finding a perfect person, it's about finding the person who is perfect for you, someone who not only accepts your flaws, but sees them in a positive way and someone you can do the same for.
Personally, I've truly been in love just once in my life. I honestly don't know if it will be forever and we've already broken up before and are now back together. What I do know is that I could not function very well without him in my life and that's how I knew it was true love, at least for this phase of my life. One saying really sums it up for me: “Love is not finding someone to live with. It's finding someone you can't live without.” I think that given enough time and determination you can always move on from someone but when it's very difficult, you know what you had with them was really something special.
Anyway, sorry for rambling. I hope this gives you some ideas for your project! I assume you're in high school? If that's the case, I have a few more years of experience (and am a bit of a romantic
) so hopefully some of what I said is helpful!
[Edit] Forgot to address the original question. Love is neither a feeling nor a commitment, it is both. Some people get married, which is the biggest commitment there is, without any genuine romantic feelings. Also people sometimes stay in relationships long after any romantic feelings have gone simply because it is easy. On the flip side, it is possible to have very strong feelings for someone, yet know they can never progress to any real relationship or for those feelings to be one sided. I think for true love to exist, you need to have both.
