You'll do fine as a couple IF you allow your relationship to be very unconventional.
Chuckle, since you're born on the first day of the month, this means that you must be an individual. You have to have clear boundaries, make your needs known, don't assume anyone knows anything before you tell them. Make very clear contracts with people.
Your boyfriend, born on the 15th day, may be a great 6 person or a very challenged on - teen days can be problematical. As a 6 person, he is very much into home, family, responsibility. Plus his month is a 6 and his year is a 22/4, so he likes the stability. He will actually like decorating, making things organized, if he's constructive with his life, because he'll know intuitively that our surroundings help our moods tremendously and a scattered messy house indicates a scattered, messy mind/energy.
He should be in any profession where he gets to call a lot of the shots or at least work with autonomy, feels like he's building something concrete, and making the world a better place overall, or at least feeing his soul.
both of you have the same life lesson number: 7. That means you are naturally spiritual - and somewhat lazy too, LOL! You both need a lot of "down time" and quiet time, and don't like your home feeing like "grand central station" all the time. So as a couple you help reflect to each other what you need for growth individually. That makes you a good team indeed. It may not always be comfy or easy, but it will be worthwhile to relate with each other.
7's should travel the entire world, learn from different cultures, often live in cultures different from their place of birth. Lots of 7's become flight attendents or couriers or international business people because the desire to see the world before they die is so great. And a lot of their spiritual growth will result from their experiences with different cultures.
Hope that makes sense! :)
