You owe it to yourself to repent to Allah; you cannot merely blame the boy who abused you especially if you did continue hanging around with him. So you need to seek repentance and ask forgiveness of Allah.

 

Repentance is not merely saying sorry. Instead, you need to feel genuine remorse over your action; you need to refrain from such activities or actions associated with such acts; resolving never to do it again and finally compensating for it by doing whatever good deeds you can afford to.

Once you have done so, you can hope for forgiveness of Allah.

 

You need not dwell on your past; for the Prophet (peace be upon him) said, “One who repents of a sin is like someone who did not sin.”

 

As for your relationship with your husband, you need to thank Allah for giving you such a man; and the way to thank Allah for this gift is to be determined to remain chaste and pure. You need to purge your heart of any attachment or thought about the boy who abused you in the first place and then focusing on cementing your marriage by taking daily steps. You should not divulge your past to your husband. Doing that more like digging up the dirt that has been buried. The Prophet said, “If dirty acts in the past have tested anyone of you, let him or her not divulge it to anyone for by doing so they are lifting the cover that Allah has placed over them.”

 

If these thoughts are still worrying you, please see a counselor/therapist who can help you in your recovery.
