Welcome to the forums sister
When there's love, it is natural to want to do things that please your partner, so I understand where you are coming from. Like others have stated here, you need to be sure you do this for you because believe me, your faith will be tested. I find myself saying this often, but, the luster of a new marriage/new relationship wears off rather quickly and it will be your faith that keeps your marriage together, so that HAS to be strong.
When I married my first husband, I was Christian and he knew I had interest in Islam (obviously, my "love" for him influenced that interest) and we got married before I became a Muslim. I eventually became Muslim on my own, in fact, we were in the middle of a fight and not speaking when I took my shahada (decleration of faith).
As you learn Islam, you may come to find that he doesn't (or does!) practice they way he should be and this can become a big issue in your marriage and it can affect your own practice or turn you away from Islam all together. This happens when we do something for the sake of a person.
If he is dating you and being intimate with you, then he is not practicing and his treatment of you will be affected in the future. If he is keeping his distance and being respectful, then his interest is a mature one with the correct intentions and a reflection of somebody who takes their faith seriously.
I have been in your shoes, so I'm only speaking from experience, not trying to be negative. My marriage didn't work out and I find this to be a common theme for women like us. So be VERY cautious and observant. I understand you are in love so what I'm saying probably won't have much of an affect

it's just the nature of things.
When I became Muslim, I didn't know much about it. I just had a deep faith in God and the little I had learned lined up with my beliefs and understanding. Be sure that you take the faith for your own self because he may or may not stay in the picture. Islam is life changing in a beautiful way and you have to come in with openness to learn.
Best of luck to you!
