A relationship is not permanent and is bound to break and no one has control over this if at all it wasn't meant to last forever in the first place. Not all relationships break smoothly, a strong emotional ordeal has to be experienced if truly love had built up. Below are some of the signs your ex-boyfriend is still in love with you;
He still calls/texts you
You broke up with him but you still receive either a call or a text from him every single day. This may show how much he is still into you and opts to relight the candle with you once again should you give him a chance.
He tries to make you jealous
He tries to make you jealous by hanging out with pretty girls, he also tries to introduce several pretty girls to you just to blatantly make you feel jealous over him.
He actively follows you on social media
He is always the first person to like or comment on all your posts on social media no matter how petty the posts may be.
He avoids dating other women after your break up
He doesn't really seem to be in another relationship after the break-up. This is a clear indication that he is still hopeful that you may consider getting back into his arms once again.
He won't be too nice to your new guy
Definitely, he won't make any new guy in your life feel welcomed. If at all he is still in love with you then it won't be too easy for him to stand watching you groove with another man.
