I suggest you get involved in community activities.
Volunteer --- every group in your community can use them: soup kitchens, homeless shelters, food banks, church groups, after school groups for kids, help coach/moderate an after school/intermural/interscholastic team.
There are also fundraiser groups for various causes; there are also political groups and hobby-interest groups.
I also suggest night school classes and clubs/groups where you can learn something: knitting, qulting, photography, cooking. See what's on line in your area.
Open a business of your own, if you have a hobby that can be a profitable one.
I am not an advocate of haing kiddoes until the relationship is a stable one and you and he have been married and together for a couple of years. The distance is part of the fly that's in this ointment; so is the fact that you're not married to him.
Until you are physically together and not separated by distance for at least 2 years, I wouldn't consider marriage until that time rolls around. I don't know the nuances of the relationship now but if you have spent little shared time together, don't marry this guy until you have a very sizable chunk of it under your belts: I suggested 2 years.
Also, do not marry him or consider marriage until you get "you" squared away.:) This is an excellent time for you to decide what it is YOU want to do with life.
