These are some possible "guilty":
1. Financial problems
Bearing in mind that money is the main cause of a split, it is no surprise that financial problems can cause cracks even between a harmonious couple.
2. Digital Shift
Nowadays it is very difficult to sit on the couch, watch TV with your partner, or go out for lunch at a restaurant without looking at your phone every 5 minutes. And that certainly fits in between the couple's romance.

3. Change in weight
A loss or gain in weight may change the relationship of some partners. Researchers say a person who gains weight gains self-esteem.
4. Feel "disconnected" from each other
If you and your partner did not have time to reconnect time, you may feel somewhat disconnected from each other physically and emotionally. It is recommended that if this happens, talk to your partners and let them know you are there and that you love them.
5. Tension on a connection
Wherever a conflict arises, either having a debate about raising socks from the ground, or any pleasant way she is wearing, can cause a quarrel among couples. Any kind of tension that is created by nothing is the "end" of sex.

6. Sex is not their favorite Sometimes people are a little cheeky in their bed preferences. Sometimes it happens that they dislike the same thing as the partner and this can cause problems, even to partition.
