You can ask yourself these 2 simple questions. 1)Does he say I love you before you say it ? 2) Does he touch your hair and/or hand? If yes to both questions, 99% he is still into you .
I know my guy still loves me just by the way he looks at me or the way he kisses me and by the way he strokes my hair when he thinks I'm sleeping those are all things he has done since we got together. Think back and if he still does some of those little things that made you fall in love in the first place or does anything special or unexpected he still loves you or is still into you. Pay closer attention to the little things I bet there is a lot of them.
