Usually the wrong feeling in your stomach is the first sign of things that things are getting worse in your relationship. If you have a feeling that something isn't right, something probably has changed for the worse. Maybe your feelings for partner are starting to change to anger and cold where it once was the warmth and kindness, and this may be the sign of something that is missing and that the relationship is beginning to deteriorate. But on the other side, it may be just another phase in your relationship you are passing through. Well, how to know exactly what is it? If it's time to break up, you can spot many signs that can show you if your relationship has reached the end or if it's possible to save it.
More fights. If you have previously agreed on everything (or almost), and now you are arguing and disagreeing constantly, it can be indicate that things are worsening. It may be even more obvious if your better half is now constantly searching for mistakes and grumbling for every little thing, and begins fights for no reason.
Passion reduction. If you have been enjoying a good sex life previously, and it suddenly stops for no obvious reason, it could indicate that something is wrong. Though it is natural to have such periods when you get involved in certain circumstances, but if partner of yours refuses your seduction over a long period – it could be a warning sign.
You are avoiding each other. Of course, it isn't possible for you to spend all the time together, but if you previously were close and spent a lot of time together holding hands, talking, having fun or kissing, and it begins to dwindle to a level when you begin to avoid each other, it's a great sign that that you aren't enjoying the presence of each other any more, and a indicate that the relationship is slowly disappearing.
Jealousy. If your partner is flirting with an obvious intention to make you jealous, it is an alarm that your partner feels insecure and requires more dedication, or it may indicate that they have been really trying to seduce someone new to compensate the loss of attraction towards you.
Interference with family members. When your partner starts using family members like children against you when arguing, then this is an indication of the danger. Involvement of family members could only create discord and create a rivalry in your relationship.
Dependence increase. When your partner is suddenly showing increased dependence on you, the problem arises, and it may mean that he or she has noticed that there is something wrong with you two and wants you to keep trying and save your relationship.
Depression or anxiety. When your partner suddenly shows fear (anxiety) or fall into depression, it is a sign of trouble. It may mean that there are unresolved issues, so if there is no obvious reason for being in that mood, your relationship can run into big problems.
Anticipation of change. When your partner gets a sudden need for a change, it is a sign that something is missing. It can show that he or she is not satisfied with the way the things are working, so the relationship could go downhill.
Spending too much time with friends and at work. When your partner begins to spend more time with friends or at work than with you and they haven't done that before, it surely indicates that something has to be changed.
Secrecy. If your spouse becomes secretive, it may be a warning. If they seem to hide something from you, like cell phones or letters, or begins to spend more time on the Internet, maybe they've found a new lover.
