Feeling Down

I don’t know why I tend to feel or overthink things with my relationships a lot more than I should be, I feel like my boyfriend may find someone he’s more interested in and leave me. He gave me no reason to feel this way, but we are opposites and we love each other but sometimes I feel like he’s gonna meet someone who is more like him and I’ll get the cold boot or I’ll be depriving him of being truly happy 😔
