Long distance na ba yung Laguna-Paranaque? If so, edi yes I've been there and no, hindi nagtagal. LDR never was for me.
It's built on trust. Siguro you have to be mature enough to be able to withstand the hardships of being in a long distance relationship. Kasi kapag hindi ka pa mature, madali kang ma-sway into all forms of tukso. Note that I used "mature" instead of "matanda" kasi, alam niyo na. Hindi talaga sukatan ng maturity ang edad.
So yun nga, mahirap but if you really love the girl, it's all gonna be worth it.
