Forgotten love remembers me again.

Are you ready to accept her? I remember the one popular saying to pacify the heart of a jilted person 'If you love someone let her go, if she comes back then it is meant to be but if she doesn't she is never yours in the first place'. Which ever way you take it, her coming back is a good sign that she belongs to you.

Don't dive into it immediately just yet. I think the best thing to do right now is to be a little open to her and give both of yourselves a chance to get to know each other a lot better. 3 years is actually a long time and both of you really needs a lot of catching up to do with each other. There's no harm on being friends and it's the safest way actually. Why? Because you get to reconnect with her and at the same time, it's a stage where both of you can test whether or not you should take it to the next level. Relationships and love takes time to grow, it is a gradual process. Just take it lightly and let things go and happen, just go with the flow.

follow your heart do what your heart want you to do. i dunno what type of the person she is,i cant judge her and it is unfair to her.
use ur rational and heart to direct what you should do, and the most important is to make sure you wont feel regret even ther happened something that you are unexpected. all the thing you do should be worth that make you not feel so lost.
