Scared of losing him

Hi well I got a boyfriend and I know he loves me but im scared that we will one day will get seperated and thats what I dont want and I told him what I felt and then he told we have to trust the lord that we will be togther always but sometimes im insecured. I feel that he is going to leave me for someon else. He havnt gave me any reasons to think like that. My problem is that I worry to much about the future. What can I do so he will forgive me what can I say? Please help me because hes really sad and at the same time a little mad because I dont trust in his love what should I do?

Only time will really prove your love / faith, and devotion to your partner. Over the years, you'll both start to feel more secure in your relationship. Don't stress, just relax about it, and it will unfold as it's intended. Good luck.
