Your relationship failed because your spouse couldn't keep "it" in their trousers. After you split up, your unfaithful ex returned, demanding another opportunity.
Most individuals will say 'No!' and not tolerate this. It's fine to ponder it. However, you must complete important work.
It is up to you to decide whether or not to rekindle your relationship with your unfaithful ex; however, you may decide against doing so if you are unable to let go of feelings of jealousy or mistrust, which is also perfectly acceptable.
The best course of action is to end the relationship if your partner's actions and commitment pledges fail to match their words. Staying in a relationship that makes you feel uneasy, angry, or inferior all the time isn't going to work out.
Although no one wants their lover to betray again, making their loyalty your top priority won't help. Focus on developing your connection, not controlling your ex. This time, you may learn to quickly address your partner's feelings of neglect or insecurity. You will learn to make your own happiness and stop relying on others. You'll recognize poisonous relationship patterns that may tear you apart.
Cheaters won't change until they alter their relationship. Thus, don't expect miracles when you give things another try. Trust and insecurity will be difficulties. You can only overcome them with fresh interpersonal tactics. Tell each other your expectations and strive toward them.
This requires you and your ex to discuss what caused infidelity. Exes may regain trust after you both see the imbalance in the relationship. Your ex's infidelity wasn't your fault. If your ex says they sought closeness because you couldn't meet their needs, you should listen and work on it to save your relationship. Since they slipped, your ex will have to work twice as hard to restore the relationship.
