When we talk about relationships in general, there are things like trust, communication, joy, sex, and adventures that define and guide a relationship. And in the case of a new relationship, managing all that is even tougher and one must be very committed to get through unscratched.
If you are looking to make your new relationship healthy, you need to stay involved with each other. Relationships often hit a dead end because couples get so much involved in their personal life and jobs giving no time to their relationships. This results in lack of trust, misunderstandings between the couples and there is a strong need to avoid this. So stay involved no matter how busy you are because your lover deserves your time and affection and if you are not doing that, you are not doing justice to your relationship.
No relationship is without conflicts, misunderstandings and fights. You cannot claim to have an error free relationship and even in the perfect relationships, conflicts often occur. But you need to keep this in mind that conflicts are a part of the relationship and they are unavoidable. So you need to learn to deal with them, get through with them, and make things perfect again. But the question is how to achieve that feat. Yes, it is not easy to get through a tough conflict but you need to think that your relationship is more important to you and for that, you have to solve your problems no matter how big they are.
Another thing that you need to keep in mind is that no one can cut himself from the outside world. Yes, getting more involved in a relationship is very important but you need to keep a uniform equilibrium between your outside life and your love life. Give your partner all the attention but do keep in touch with the people from the outside world.
