Most Helpful Guy
Love him, support him, and make it known that you still love him. Guys need some personal time, and that's ok, so when he needs some time give it to him.
A mistake some people make is they stop trying. Just because your with him doesn't mean you should stop trying to "win him over" just as he should never stop trying for you. Go on dates, complement each other, let your partner know that you desire them. A thing most guys want is to feel needed; we want to feel like we have a purpose and that you need us. Make him feel like he's wanted and needed and he will keep with you
