How can i rekindle the love in my relationship?

I think your guy needs some personal space. Yes at times we might feel he doesn't love me as much as i do or miss me as much as i do, but guys can't express their love that easily and freely. Try to be normal to him and please don't crib that he doesn't love me or miss me, just be yourself, you be good to him, speak to him, send him short notes or sms telling you love him and miss him. he himself will come back to normal.
