Search Results: getting a girl's number

So I’m dating this guy that I wasn’t attracted to in the beginning ( which is why I took two years before I finally gave him the chance to take me out). So few months ago this girl moved to my house (he was still courting me) he asked her for her number and social media and they started talking, I found out that through her by accident. I honestly don’t know what kind of conversation they were having even though I told her that he was courting me She still gave him her number. So I planned since December of 2017 to go out with him in the beginning of 2018, once i was done with something that I was doing. So even though I found out that he took her number I still went outvwith him because I felt like he really loves me. So I keep having this gut feeling that he likes her a lot and I know for a fact that she likes him. When we’re in church I’m always ministering so I m always seating in a separate place, he keeps getting up and seating on the same bench as her. I still catch him looking at her, and when I’m in a room with both of them I feel a bad energy coming from both of them.., she starts acting weird and he keeps secretely looking at her. Should I be worried... even though now we are dating I feel like I should just leave him bcoz I don’t want a broken heart. What should I do?
