Your relationship can never stay the same if one of you cheats. Some things are bound to change, if not all the things. Honestly, majority of couples do not make it work after one of them is unfaithful. However, we are not trying to persuade you that it is impossible, we just want you to know how your relationship will be different after that.
You will probably not trust your partner as much as you used to. Or, you will find it difficult to trust him again. If you are determined to make it work again, be ready that it will be a long and difficult journey.
Your confidence will be lower. You will perhaps start doubting yourself, although you did not have any doubts until you found out.
You will be stressed and you will find it difficult to focus on your job and other things apart from your relationship. Cheating is serious, and it requires your attention.
You may find it difficult to enjoy sex afterwards.
However, if you manage, infidelity may make your relationship stronger than ever. Although, we do not advise you to try it.
Well, what else can we say? Good luck only! And strong nerves. You should definitely try your best to make things work. But only if the relationship is worth it.
