You are NOT over reacting. A person that drinks to get drunk and to be oblivious is a big RED FLAG. The fact that you don't see him often and he's done this more than once, is another BIG RED FLAG. You already know this, and it's the reason why you're so upset. I'm sorry you're getting these red flags but the reality is that dating when you're young is meant precisely for you to find out what you'll be happy to accept and what makes you unhappy and not accepting of certain behaviors. Instead of being on the sunny side of street, you've been put in the position of watching a person who may or may not wake up after a bout of drinking. It happens. What if he put his life at risk, and you were the person that had to watch him die? What if you had to wrestle with blaming yourself for the rest of your life that you didn't take him to the hospital because he became unconscious? How would that affect you for the rest of your life? He's asking too much if he wants you to be his caretaker while he uses alcohol to escape the stress of becoming a man. That's not what your role should be in his life. Demand his full attention with a couple of drinks and you'll know you have his heart. Otherwise, you'll have good reason to wonder. Sorry if it's not what you want to hear.
Well, first things first. I would let him know that when you DO get to see him, you have certain expectations, that he does not have more than one or two drinks. If he can't do that for you, he's just not that into you, or he's starting to have a drinking problem. Keep it simple and be logical. The fact that he works and is going to school and you don't see him often SHOULD mean that when he does, YOU are the priority. Don't you think? Otherwise, are you willing to be his caretaker while he is being pressured by friends, and de stresses with alcohol? Maybe when you and he are able to spend some time together, since he's so busy, you could do so without his friends there pressuring him into drinking (that's what i got from you saying his friends are pressuring him). You might as well learn now, that it's your job to teach others how to treat you, and making excuses for their behavior is counterproductive to that purpose. A man needs to respect the women he's with always, or he'll tire of the relationship and look for someone who respects themselves enough to only expect his best when they're with him.
Getting drunk and passing out is a Major Red Flag. Having "plans with You" but getting drunk and passing out emphasizes the Red Flag. He made the 'choice' to get drunk instead. Recognize that He made a choice !! He has "some issues" - but so do You, so do I, and so does everyone. We ALL have issues. It's not about "issues", it's about behavior. He makes plans with You but doesn't 'follow through' - those are choices He is making. You have been with Him for 2 years - (2 years can quickly become 4, then 6, etc., etc.) You say "I learn to accept Him and luv Him for who He is" - if that were truly so, sweetheart - You would not be here expressing concern for Him not following through on Your plans. This is making You unhappy and You are absolutely right to want more from a relationship. You need to realize what You see is what You get. If He was inclined to follow through with His plans with You He would make the choice to do so. I'm not suggesting that He doesn't care for You in some way but I am saying You are not His priority. Love is a choice - You are 'choosing' to love Him in spite of His short comings and Your own unhappiness - You are making Him Your priority but He is not making that same choice as regards You. I would imagine He knows You have been unhappy with this situation ?? yet it continues ??
So, how old are you guys? Clearly he isn't valuing you more than partying. Which is insulting. You want to be with a guy who puts you first. Maybe not 100 percent of the time. I think everybody needs time to cut loose and hang with friends personally. I've been married a long time and still afford my husband those nights out with his guy friends. But this sounds like a frequent pattern. And his drinking may be problematic.
Getting drunk to the point of unconsciousness is pretty much a relationship ender, as far as I'm concerned.
