Love is a strong feeling and there's no doubt about it. But you have to ask yourself "is this what i want? is this a type of person i feel like i could be with for a long time? am i really comfortable with this person? how strong are my feelings for this person?" things of that type. You have to oppose what you feel to see if you feel strongly enough to overcome those opposing questions. And if you can then maybe in fact you are in love. But I don't know exactly how you feel so I couldn't for sure tell you. Hope i helped.
