Breaking up with someone you have spent time with is never easy, it makes you feel bad about it because of course, you have some remaining feelings towards him/her.
This is how you will know that you are not yet over your lover:
Feeling nostalgic
You clearly are not over your ex when you miss the good times you were having together.
Stalking him/her on social media
The easiest way to know about the going on of your lover is through social media updates.
Checking his/her WhatsApp profile and status
Probably you want to find out if they really have moved on or if they are happy without you.
Acting jealous
Do you feel jealous to see your ex with someone else? Well, if yes then you know the answer.
Drunken calls
When you get wasted at the club, at the pub, whom do you think of calling? Is it your ex? Then if that is what you do, it means you are not yet over him/her.
In conclusion, if you broke up with your love and you are still single, maybe you have hopes that he/she will come back then it means you are not yet over them.
