A sign from God!? Help!!

Saturday morning, I attended a New Year’s <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> church service with my aunt. Now 3 weeks ago, I found out my boyfriend of 4 years has been cheating on me terribly. It was bad and the things I found out was gut wrenching and heartbreaking. When I found everything out, I confided in my aunt as I was with her the next day. Now he has begged for me back and swore up and down he is changing and doesn’t want to lose me and how he’ll do everything under the sun to make it right and earn my trust and keep me. So I’ve been hanging with him and we have been reconciling but ofc I’m wanting to take it slow to protect myself and after everything happening, I’ve had doubts in the back of my head and worries. I even had a dream like 5 nights ago that I found out AGAIN he was doing the same thing that just got exposed. Now once church ended today, my aunt took me around to introduce me to some members and there was one lady she stopped to speak to. I was introduced and the lady kept telling me how pretty I am and how sweet I seem but then she kept staring at me oddly and it was becoming awkward then she looks at me again and instantly blurts “Be careful” so I looked at her strangely and she asked “are you dating?” And I told her “yes sort of” and she proceeds to shake her head and says “ everything that glitz isn’t glam…he may seem like gold and the one but he is not intentional and does not have your best interest at heart. God has someone much better for you” and my body kinda started trembling and I looked at my aunt bc she knows about my situation so I’m thinking she told this women something and this is like a prank or something. My aunt says she hasn’t talked to this lady in months bc she’s been habitually going to service at the other location. I’m very shaken up and emotional and had to hold back tears. Then the next morning on Sunday, my aunt went to service again but without me…she came back and told me that her pastor approached her asking about me and long story short, saying the same type of things the lady said to me. Now my aunt hasn’t been the biggest fan of my bf, sad to say she judged him based on looks, so I’m not sure if this is something she orchestrated seeing as this is HER church and she knows these individuals or if it was truly a sign or wake up call from God that he isn’t going to change and I need to let him go? I’m so confused and torn bc this boy has broken down and cried to me and spilled everything and put it all on the line that he would NEVER do this again and that he is 1000% committed to fixing this and doing right by me and I want to give him that opportunity. Please I could really use some advice
