Make a sincere comment every here and then to your ex.
Let's say: if your ex is putting up something new, you can compliment on the attire.
Bring up a conversation about some good times you spent with him back in the days before the breakup.
Talk about the most interesting part of your affair with him, which will show him the reason why he should have you again.
You can also flirt a bit with some other guys but don't overdo it.
Make him envy you a bit and show that you are a person worth working for.
Attempt to be his pal once again; it might be that he also needs you back.
Take things gradually.
Allow some time.
It's possible that your ex is still upset and require sometime.
Therefore, dashing into anything is likely to send them away.
Don't give your partner the impression that you are desperate and dying to be back with them.
It can only deteriorate the condition of worsen things.
Don't even act like you need them back.
Like I said previously, there is need to show her unconditional love.
And still, nurture your thoughts and hobbies as if you are wholly in charge of your personal pleasure.
You actually do not want to relay on someone else to feel the tranquility and joy you deserve.
If you let this pattern become part of you, you will see that your partner would be the one afraid of losing you to another person.
