Should I ask him what happened or just leave it as is? If he really wanted to see me, he would have made the effort despite my responses right?

In my view, six dates is not nearly enough to make up one's mind about whether to commit.
Committing is for life - so you need to know someone very, very well before making a vow of fidelity.

There are some ways to speed things up when your biological clock is running out of time for trouble-free baby-making.

Make a list of your absolute no-go attributes in a partner. If smoking ciggies is a big deal for you, make sure he doesn't even before the first date.

Establish the basics on or before the first date.

~ Do you share common values on things like honesty, responsibility, kindness, manners, beliefs, politics, class, race, gender equality (or otherwise) and so on? The more of these you share, the greater the likelihood of long-term success as a couple. If you share few or none, expect conflicts and tension.

~ Are your careers (work hours, workplace, ambitions and goals) compatible? If there was a change that was incompatible, who would make the sacrifices and how easy would it be for that person to cope with giving up their goals? Do you like, respect and admire each other's goals, (so you can be mutually supportive.)

~ Do you both want children? If so when, and how many? And do you both agree on the basics of how to raise kids?

~ Are you both committed to personal growth and development? Do you have the determination to be proactive about it? Can you both see a primary relationship as an excellent way to support each other in maturing?

~ Do you share common interests and tastes, for instance, in music, movies, shared exercise or hobbies?
Do you also have differences in interests and goals that will bring freshness to the relationship?


On the second date you can go deeper, and explore possible things that might not be so good.
- Does either of you have an addiction? (Remember most addicts lie about this, so watch behaviour carefully - can he have an evening without drinking.)
- Does either of you have a disability, or a genetic disorder? If so, how would you both adapt?
- Does either of you have history of trauma, crime, or mental or physical illness? To what extent does this information affect your choices?

On the third date you could ask about sexual history - have they had any sexually transmitted diseases? What is their current sexual health status? Would they (and you) be willing to take an AIDS test and wait (celibate) for 3 months?
Have they had many affairs or only a few? How long? How did they end? Was there a pattern? If so what was it? Does he seem open and honest about these things? If he's reluctant to say, that's a bad sign.
Look for signs of controlling behaviour. Is he finicky about being exactly on time? How does he handle it if you are 5 minutes late but don't ring to say so? How does he handle it if you are half and hour late but do ring?

If you get past all that, and then after dating each other for a while, you feel things are going really well - then you probably have a good basis on which to build a serious relationship.

But remember, when people fall in love, they are blind to (or excusing of) the other person's flaws.
By the time two years have elapsed, the bliss hormones start to fade; each person starts to see who the other really is. The cracks and the dark sides start to show.
This is the make or break time. If you have good communication skills, each argument will help you understand each other better and grow closer. As in-love fades, real love starts to grow.
But if neither of you have good skills, things will start to fall apart - and then it's better to break than to continue into long term misery.

A good test is to spend time travelling together, preferably in close confinement in a tent or caravan, and with problems to solve such as in camping or abseiling.

I'd say never commit before spending at least two years together - and certainly don't risk having kids until you are both sure, and both in agreement.
