I think I want to change my views on god and my boyfriend is extremely uncomfortable

this is long. sorry.... So growing up i never had much influence of god. My mom would mention god sometimes and my grandmother has very strong ties with him although she doesn't push it. she talks of him as if he were just some man she loves and in passing convo and that's that. I've always been really unsure about god and that has continued into my adulthood. I've been with my boyfriend for three years and he is not AT all comfortable with God. He thinks it's just a figment of people's imaginations. he's more of a Universalist and believes in energies. Which is fine ! I've always loved the view points that he has and find them fascinating and fairly logical. I've found positives in Buddhism, Taoism, all sorts. somehow though I always come back to god. No titles. No specific religion. just a wanting to have some sort of relationship with God. I don't know what I believe really and I have this sense of understanding that is so great it makes IT hard to say that all these perspectives are wrong. But regardless of what I believe or choose to believe IF I wanted that godly relationship. that should be my choice. It's be mostly just adding more for my own inner peace. looking outward to god during meditation instead of always looking inward.... I'm not pushing ANYTHING on him and honestly don't think itd change anything but he's convinced it will. that it will change me and eventually bleed out and obviously change how I raise our children. I'm not super social and church has never been my thing. I just think god is such an amazing way to show love faith and hope . a way t sort through my own inner turmoil and have someone to look to and talk to free of judgement . I think that my children could benefit and learn through god as well. i dont think that's so wrong. and I've always told him and thought that, regardless of my own beliefs. I'll show them not just "my god" but many gods and help them learn. as long as they always know that god is love... I guess my main concern is I should feel loved and accepted no matter what I choose to believe , yet he's making me feel uncomfortable and insecure about it. I shouldn't be scared to voice my opinions because I never would hinder him in anyway. i guess I'm rambling.... advice?
