If something hurts you inside, it's not too much love in you.
It often happens to suffer "out of love" - but this suffering is attributed erroneously to love. As I like to say once, "love must not be condemned for human error."
Love can not hurt you, it can not make you suffer, it does not make you a miserable person, nor does it put you in depression. Love can make you happier, better, cheerful. If you are not that, it means two things: either that you have too little love in yourself, or that something else has entered - which is often mistaken for love - or a result of love. The only result of love is that it fills you with something wonderful and good. Both! Everything else is a result coming from somewhere else.
If you have the impression that you miss it, that you can not without it, that you love it too much and therefore suffer now, then you have also fallen into the trap of a confusion from too little understanding. When your mind is dark, love is much harder to shine.
How about staying full of love, even if she is not? Not a directed love, but one that simply is in you, to fill you. And even change you. A lot of people do not understand that usually the love you feel about someone has little to do with that person. This conclusion is reached after a while, when the thought "did I like it?" It was something of you out there in her presence. But if her presence is no longer, that of you still exists. The fact that you prefer to focus on its lack and not on the huge presence in you is an unconscious choice that your mind does - not the heart. The heart longs for love, not for her.
And many times, if it comes back into your life, you get the same result. Sometimes with even more torment, with even more frustrations. Because nothing has changed in the meantime - neither to her nor to you.
If we wanted to be more loving and less tied to someone whom we think he had gone with our love (what a fun idea), things would be different for us. But also for those around us. Because it's hard to stay indifferent when someone radiates love. If at that moment you open your heart or put on a layer of protective cream against the radiation of love, it's your choice.
