Ah, to be young again. Ok, so he faked being sick to hang out with his ex at a party? Did I read that right? This post was kind of hard to follow, but it sounds like you’re dating a boy and not a man. If he was actually sick it was probably stress! First, six months in a relationship is not crap! You are both still getting to know each other, and while strong feelings may exist, you both sound young, and have yet to live through life’s trials and tribulations. Love is way more than a feeling, it’s also actions. I’m not saying to give it up, but it’s important to learn from mistakes, both yours and his. The truth is, just by going by what you have said, he’s seeing his ex again, and has been in contact with her for a while without you knowing it. If you keep “blowing up,” at him, he’s going to feel the need to hide that stuff from you, because he is doing wrong, and he knows it. This situation should’ve never happened in the first place. If he intended to go back with his ex, he needed to break up with you first, or at least let you know he wants to be friends with her if that’s the case. Being open and honest is the recipe for a healthy, long lasting relationship. He wanted to spare your feelings because he knew how you’d react to him having contact with his ex. Someone who is ready to be in a committed relationship would’ve not tried to hide anything from you, he would have sat you down, and told you exactly what was going on. This dude is a weak chicken. Second, the minute he knew your family member was in the hospital, there should’ve been a phone call no matter what he was doing, or who he was with. Here is what I have learned in life so far when it comes to relationships. Treat people like you want to be treated. Have fun, life is too short. A strong relationship is not 50/50, it’s 100/100, and takes work sometimes. If someone is going to do you over, then that is exactly what is going to happen. There is nothing you can do about it. You move on, and start dating someone who will treat you like you deserve. The past is the past, and being scared to start a new relationship will only help you pass up somebody really great. Only you know the answer on whether or not to work it out with him. Trust you gut, it’s usually right! Good luck!
