My Boyfriend has ADHD HELP!!

Hey so my boyfriend of 2 and a half years has Adhd. At first I didn't think it was a big deal and in all honesty I just thought it meant he just had a little more energy than most people. However, now certain things about his adhd really get to me and I don't know how to feel about them.  For example, he seems to have no filter.  He says whatever is on his mind and sometimes things he says can be hurtful. He's not a hurtful person but he just tells me things that most bf's wouldn't tell gf's. Like his sexual temptations, what he would rather be doing than talking to me, or personal details about his family or his past relationships.  A lot of the things he says really affect me.  It can also get annoying when he doesn't concentrate on what I say or when he forgets very sentimental details about our relationships.  We get into a lot of intense arguments. We are also in a long distance relationship so it can be harder to communicate over the phone. We see each other at least one weekend a month, and for winter/spring/ and summer vacations.  He recently got off aderol because he said it made him cranky and is taking a milder medication.  However, we just got into a fight because he had a fight with his parents.  He came to me when I was stressed and started complaining about his depression and his anxiety and I just wasn't ready for it.  He also has this habit of picking his face and it drives me crazy sometimes. 

Despite all of this I love him like crazy and we have talked about getting married one day. There are a lot of things about him that I love and make me think he is the one. For example, he is very romantic and helps me when I am having problems.  He is very affectionate and forgiving and he can always make me laugh. I also have never met a man who wants to be a father as much as he does.  However, these problems that he says are caused by adhd worry me. It feels wrong to break up with someone because they have adhd, but then again I have to think about my future happiness. I guess I am scared that the intensity caused by adhd will only get worse and make me miserable.  

I could really use some advice from people who know more about the subject.

P.S- We are both 20 years old and he is my first bf
