Love can't be check just it can feel.

time will answer it all....

If he really cares about you very much.

If he is kind, considerate and respects you, it's certain that he loves you.

you will not know it much by simply asking him. Talk is cheap. It requires a long time and a lot of factors to prove that your partner really loves you. If both of you stayed being together for two years or more, I think that's the time you can prove that he really loves you. :)
