Interfaith?

hello, I am a Muslim girl my last relationship even though it’s haraam I am aware and God has shown me every time why it is haraam. I just wanted to know everyone thoughts on the topic of interfaith relationships or marriages. Now that I am feeling much stronger with my deen.

At the time I kept seeing like videos that if you are with a person, that’s not the same religion as you it’s most likely because you don’t feel as strong in your faith and I was just wondering what everyone thought about that. Is there any truth to that?
