Keep communicating with your partner and tell them how you feel. When you've been together for years it can be easy to assume that your partner can read your mind. Talk to them about your day, about things that are on your mind, and about your relationship - communication is the key to any successful relationship.
Listen to your partner
Make sure your partner gets a chance to speak about their experiences too. Listen carefully to what they have to say and take their concerns seriously. It may sound simple, but a common reason for conflict in a relationship is poor communication.
Try to avoid arguing at times when you may feel tired or stressed as things can escalate very quickly. Give each other time to mull over the issues that have been raised. It is healthy to have disagreements but if the situation is becoming destructive or you are both becoming overly distressed, try to take some time out.
Make time for you as a couple
Work and children can lead to very full lives and 'couple time' can seem like a distant memory. Take time out as a couple. Consider reserving a regular 'date night' for you and your partner. Spending couple time with your partner on a regular basis will help you stay close to them.
Make your partner feel special
Little things can really go a long way to showing your partner how much you appreciate them and how special they are to you. We're not talking grand gestures here, but the little things like offering to do the school run for a day or allowing your partner to enjoy a spa treatment or a hobby.
When the problems are growing
If things just aren't getting any better, don't be afraid to look for professional help. Sometimes it can be easier to address problems with the help of a neutral professional who is experienced in helping couples work through their difficulties.
