My advice is that there is no advice, heartbreak is a difficult thing to actually deal with. Conversely you can suppress the feelings via whatever means you prefer eg alcoholism, workaholism, rage-aholism, as some on this thread appear likely to have done. Ultimately the only way out is through and this is a path unique to every person. As for the texting, just stop. There's no amount of alcohol that can make you forget that you'll regret this. More likely it's an excuse to self-flagellate, speaking from my own experience. Oh and one more piece of advice: don't ask engineers for emotional advice, we are notoriously stunted in this area.
