Either one of two things has happened if youre trying to repair your relationship, either you have broken up with your partner or the relationship is falling apart and you fear it may be over soon. Dont panic because that will not help you and can almost certainly work against you as panic and desperation is not a great look for anyone in a relationship.
It is absolutely vital that you make the decision today to take every step necessary to ensure that your words match your actions. Saying you are going to make a move, and not doing it, or doing something different is a form of lie. As time passes, this may cause trust issues in a relationship.
Whether or not its another way around and you have now been dumped then you need certainly to stop texting them, stop calling them and stop sending them emails and instant messages begging for them back. This can be a stressful time I am aware because I have been there, but all of your doing is making it worse rather than helping repair the relationship which is our goal here after all.
Do not keep secrets from your partner. If you know something worth addressing, make sure your partner knows about it, regardless of how trivial it might appear to you. This is a lot better than having your lover discover this information independently and then wonder why you did not inform them.
Now that the dust has settled continue living a normal productive life and do not contact them for quite sometime. You might find your relationship finds its way back together once you least expect it simply because your ex will be missing you when you show no desperation towards getting him or her right back.
