RUN for your life!!!!!!
Not only should you break up with him, but you should alert Pastoral Elders or a trusted pastor over the sin you share and repent asap and also what he is asking of you. In order to obtain the honour of serving in church with the goal of being in some form of leadership position (which all men are in anyway), men need to meet the character qualities of 1 Timothy 3:
Now the overseer is to be above reproach, faithful to his wife, temperate, self-controlled, respectable, hospitable, able to teach, 3 not given to drunkenness, not violent but gentle, not quarrelsome, not a lover of money. 4 He must manage his own family well and see that his children obey him, and he must do so in a manner worthy of full[ respect. 5 (If anyone does not know how to manage his own family, how can he take care of God’s church?) 6 He must not be a recent convert, or he may become conceited and fall under the same judgment as the devil. 7 He must also have a good reputation with outsiders, so that he will not fall into disgrace and into the devil’s trap. 8 In the same way, deacons are to be worthy of respect, sincere, not indulging in much wine, and not pursuing dishonest gain. 9 They must keep hold of the deep truths of the faith with a clear conscience. 10 They must first be tested; and then if there is nothing against them, let them serve as deacons.
This is the standard of all male leaders, and since in Hebrews 13:7 tells church members to imitate their leaders, this list of behaviour is held for all men in the church, and your boyfriend fails miserably at this test. He has already cheated his future wife (which you do not hold title to and might never), hes preaching a false doctrine with his outward behaviour when his heart is thinking evil, and he is sexually abusing you by expecting intimate privileges of marriage without having earnt anything by being faithful to Gods standards.
