In either case, you are just going to get hurt and not get what you want; a committed relationship with your ex.
If you are serious about getting your ex back, or being happy in your life, make sure you never force them for being friends or even decline their offer to do so; at least, not until you are done with step 2. The fact is, if your ex starts dating someone else soon after a breakup, then it’s definitely a rebound relationship. In fact, it just means that after you broke up, your ex had a huge hole in their life that they are trying to fill with someone new.
It’s not some mind tricks and cheap gimmicks that you will use to trick your ex into getting back together.
If you are planning to trick your ex or force them into being with you, you are just going to end up in another miserable breakup.
Your ex has decided to breakup with you for a reason and every time you express your infinite love for them, you are making them think of that reason in their mind. Do you hope that your ex will see them and come back to you?
