It may happen that you still have some serious feelings for your ex but it is really scary to directly ask them to come back or to show them that you are still into them. However, if you take your time to learn from the past then you can easily get them back.
These three mature ways will guide you to getting back your relationship;
1. Get to understand the breakup
Take your time to understand the breakup, how both of you contributed to it. It is true that trouble in relationships don't come up unexpectedly but take time to build up. Sit down and think back before you attempt to bring back your ex because you may be trying out something completely impossible. Research indicates that the number one cause of break up is poor communication, if this is the case then you can resolve the matter and get back. But with staff like cheating, it is really hard to get back.
2. Recall who came up with the idea of break up
Think of whoever came up with the idea. Was it you? If so, did you think before deciding on that or you said it out of anger or ego, do you regret? If it's your ex, did they provide reasons? Or was it a mutual decision? If it was you who initiated the break up then getting back would be easier compared to if it was your ex. However, it is still possible to get back should it be that your ex was the one who controlled the breakup. Gather reasons from them and make wise decisions like apologizing should that be applicable.
3. Interpret your emotions
Do you miss your ex? Do you think they are missing you? Do you think they regret having left your side? Did they make you feel better about yourself? Do you miss having a lover? You should not rush to asking your ex back before taking some time to think over it. Examine your emotions and decide whether or not you should be with that person. Remember relationships that are meant after a break up often suffer lack of trust and with no trust then there is no love.
Be keen with this because if you make rushed decisions on bringing back your ex and it happens that you be successful yet you were not contented with some staff in the relationship then you will have trapped your own self.
