Even if you haven't exchanged marriage vows, you still know that there are unwritten and unspoken vows between a couple in love. One is that you can always rely on each other, and this is certainly a good test if you're trying to figure out if your man is in love with you. If you know instinctually that you can count on your man at any time of the day or night, the chances are high that he's head over heels.
Your guy is the type who is likely to drop everything he is doing if you need his support or help. If he can't be there, he'll manage to find a solution from afar. That's just the kind of person he is when he's crazy in love! He also loves that he can count on you, too.
