He doesn’t want to hurt me...

Little backstory, my BF and I have been together since high school. Since we were 18, and now we’re 22. We have had intentions of getting married since we started dating, and now the plans of getting married are more serious. We agreed that we would get engaged sometime after I graduate with my BA, which will be in about 2-3 months 😁

However, in the time we have dated, his parents who have been married over 25 years are getting a divorce. No one saw this coming. His mother just decided she didn’t love her husband anymore, and left to live with her brother in another state for a while. Kinda leaving everyone shocked and stranded. Thankfully, my BF is starting to heal from this and is trying to move on and learn to love his mother again, which I am super proud of him for.

The dilemma... this has severely changed his look at marriage as a whole. I know that he still wants to get married and have children and grow old with someone someday. He loves me very much and has told me that he isn’t scared of marrying me... he’s scared of messing up a good thing. Like how his mom did. He says he’s afraid that he might change and then hurt me... I don’t believe him when he says this. He is so genuinely sweet and kind and loving towards me and I know that he was made to be a husband and father.

How can I be supportive of him during this time? What can I do or say to reassure his that he won’t turn into a monster? Or has anyone else gone through this situation as well?
