Salaam,
I agree with recluse, this is because the life after marriage will not be same as it is now [before marriage]. It gonna be change totally. I am saying this all based on my own personal experiences. Its not that easy how we think, there will be many new issues taking birth everyday, so be careful.
Unfortunately, I saw quote of 2:221 without pointing out what exactly is the message in it.
2:221
وَ لَا تَنۡکِحُوا الۡمُشۡرِکٰتِ حَتّٰی یُؤۡمِنَّ ؕ وَ لَاَمَۃٌ مُّؤۡمِنَۃٌ خَیۡرٌ مِّنۡ مُّشۡرِکَۃٍ وَّ لَوۡ اَعۡجَبَتۡکُمۡ ۚ وَ لَا تُنۡکِحُوا الۡمُشۡرِکِیۡنَ حَتّٰی یُؤۡمِنُوۡا ؕ وَ لَعَبۡدٌ مُّؤۡمِنٌ خَیۡرٌ مِّنۡ مُّشۡرِکٍ وَّ لَوۡ اَعۡجَبَکُمۡ ؕ اُولٰٓئِکَ یَدۡعُوۡنَ اِلَی النَّارِ ۚۖ وَ اللّٰہُ یَدۡعُوۡۤا اِلَی الۡجَنَّۃِ وَ الۡمَغۡفِرَۃِ بِاِذۡنِہٖ ۚ وَ یُبَیِّنُ اٰیٰتِہٖ لِلنَّاسِ لَعَلَّہُمۡ یَتَذَکَّرُوۡنَ2:221 And do not marry polytheistic women until they believe. And a believing slave woman is better than a polytheist, even though she might please you.
And do not marry polytheistic men until they believe. And a believing slave is better than a polytheist, even though he might please you. Those invite to the Fire, but Allah invites to Paradise and to forgiveness, by His permission.
And He makes clear His verses to the people that perhaps they may remember.Points to be taken into consideration from the above aayat:- Do Not marry polytheistic men [in this case, remember its a clear order from God].
- And a believing slave is better than a polytheist [do you see the comparison?].
- Even though he might please be a wonder to you. [If you look at the Arabic word, it says "aajabakum" means "even though he might be a wonder to you", hope you know what wonder is, like seven wonders of the world].
- Those are the ones who invite you to the fire [do you have guts to take this risk?, remember! The Warner is Allah, our TheCreator, TheKnower of all].
- Allah made his aayaats clear for those who remember [ending of this aayat is reminding us to remember what is said].
If he agree to accept what you believe and become a believer [in God alone], then surely you can marry him. I suggest, don't give importance to a guy over the path of Allah. Just a suggestion, you can throw it away if you don't like.
May Allah increase us in knowledge and guide us to His true path
