Being physically intimate with your partner is a way of expressing love. Sometimes it is necessary to solve a problem.
It is very important to spend time with each other for a good relationship.
But if your partner is spending more time with his friends and is not giving you time, then it means that he wants to go away from you.
If your partner is not clarifying to you what he is doing, then it can be a sign that he wants a breakup.
There may be some external reason for your partner to do such thing like family problem and work stress etc.
Usually it is very important to talk about future plans in partners. This shows that your partner is seeing the future with you.
But if your partner is not talking about future plans and not taking interest in your plans, then it means that he is not seeing the future with you.
Whenever you have any problem and you ask him for help, he will not show any interest.
It is very important to have contribution from both the sides in any relation. If your partner is not taking interest then he wants to breakup.
