Relationship is a two way street. Dapat kayong dalawa yung gumagana sa relationship, hindi pwedeng ikaw lang o siya lang. Ika nga nila , “It takes two to tango.” Dapat kayong dalawa yung nagbebenefit sa relationship niyo. Kasi being in a relationship means interconnecting yourselves and merging as one. You grow as one and develop as one into becoming better versions of yourselves. Take a seat ka muna and ponder, “Does this relationship still do me any good? Am I still growing and becoming a better person sa relationship na ’to?” When you think you have found the right answer, assess them and weigh things again and again. If you think that it is still worth it, take away some of the heft you're carrying alone in maintaining the relationship and talk with your significant other about it. Ask her to be with you, support you, and be by your side in strengthening the pillars of your relationship. Pero, the reality of uncertainty still stands clear. Much like two sides of a coin, there's always the desirable possibility, and there's the, rather undesirable one. Paano kung na realize mo na hindi na worth investing your time ang relationship na you're in? Let me tell you something.

When we fall in love, we tend to build the foundation of ourselves with them as the center; as if our very own world only revolved around them. And so when that person leaves, everything seems to fall apart too, for they were the reason why we build ourselves
And when everything's all gone, remember that you always have yourself. From scratch you can start building again, and you'll reach the stars once more... only this time for yourself.
And if "it" happens again and they decided to leave once more, trust me, you won't shatter and fall like before; for you have learned to love yourself more
Kaya always focus on yourself more. Do not do things for them alone. Do things for YOU too. Go, have your own likes and passion. Don't ever lose your sense of self just because you love someone so much so much

Never forget to always leave something for yourself. I wish you the very best, OP.
