There will be times in life when others will do things that may hurt you, and cause you pain or discomfort in some way. Many times people will show signs of remorse, and be apologetic. Other times, they won't. When people don't show any sign of remorse when they've clearly done wrong or hurt you in some way, sometimes we simply need to suck it up, and live with that pain, despite not having closure. Unfortunately, we don't always get the apologies nor the closure that at times, we clearly deserve. However, we need to remember that we have the power within ourselves to be strong, resilient, to let it go, and forgive them anyway. It's important to make peace with situations, even when you don't have the power to change them.
When it comes to dating, many times situations won't work out, and not everyone will end things cordially, or on a kind note. During those times, it can be a tough pill to swallow, but we need to swallow it anyway. We need to let it go, and keep in mind that despite someone's lack of kindness and sensitivity towards you and your feelings, you're entitled to feel the way that you feel, and you should try to do whatever you can that's positive to lift your spirits. Sometimes that can be challenging. Especially if someone was cruel, harsh, or insensitive to you. However, you should be good to yourself, because you deserve it, and it's important to recognize that the problem or issue is in the other person. When people hurt you without remorse, they need to work on themselves. But, you can only control your own actions and thoughts. It's best in situations like that to let go, and forgive them, even if they don't admit to their wrong doings, so that you may be at peace, and move on.
If you're in a relationship where someone that you love has hurt you, and they not only don't apologize and show no sign of remorse, but they become distant, cold, or indifferent, and as if they don't even care, you should take some time to reevaluate your relationship, and decide whether or not they're the right match for you. When someone truly loves you, they'll not only apologize when they're wrong, but they'll never want you to feel pain in any way, and they'll try to fix what they did (if possible), or make up for their wrong doings. Having said that, sometimes people make mistakes that can't be fixed. However, whether or not things can be fixed, corrected, or made up to you in some way, the other person should be remorseful and apologetic. Unfortunately, like I said before, we can't expect things to always go our way. If something was done to you that's so harsh or bad that it feels unbearable to live with, then end the relationship, and move on. It's simple, you're not married, and it's just a relationship. That's what relationships are designed for. They're to discover how well people can get along, and if they are truly compatible.
Despite whether or not you keep dating someone that's done something wrong to you or hurt you in some way, the decision is your own in how you handle it. Whether you keep dating them or decide to stay in the relationship, and whether or not they're apologetic, you need to decide what's best for you, and only you can do that. Either way, if you're going to stay in a situation, you must do so with a forgiving heart, even if they don't apologize. You can't let your hurt build up, because it will not only drain your energy and numb your love, but it will turn into anger, resentment, and you may start to become bitter. Nothing is worse than being in a relationship with someone that has unresolved hurt and resentment towards you, so you need to let it go, and forgive them if you're going to stay with them. If you're not willing to let the hurt go, and forgive them, you should end the relationship. You must think to yourself... How much do you love the person, will you be happier without them, and whether or not you can let go, and forgive them, so that you may both have peace and harmony together.
