Is My Girlfriend A Threat To Me?

Dear newsblog, I need you honest advice on what to do. I am still a young man and any mistake now will have a grave effect on my future. So please, help a brother. 

Be objective and consise please. It is a long narrative.

I have a girlfriend whom I have been dating for up to 10 months now. She has all the qualities of wife, friend and a partner. I mean, she prays for me, supports me and do many things that places her above average. 

I've two issues that are bugging me; 

First is, I just graduated from the University and started to follow the road map I designed for my life. I am hardworking, so I started doing business immediately after my defense. Interstate exports of perishables. While I was in school, I made a lot of money doing designs for students; I am a UI/UX designer. The problem here is that I can't account for all those monies I made. A lot of expenses especially for my girlfriend. Even till now, I am supposed to send her some money but will I continue like this? I need stability in my business and need to save more and need capital for the last mile logistics company I want to set up next year. 

Second issue is; I recently returned from an event I attended in Lagos some days ago, I came back very late and was grossly tired. While we were chatting, she asked me some questions which I told her I was very tired and eventually, I slept off. My phone beside me till the next morning. Fast forward to yesterday, I told her of my intentions to concentrate more in building for the future - it doesn't mean our relationship would be off. She started asking questions like "do you need some space?" "Am I bugging you?" She also said I don't "speak her language enough" language here is bonding, intimacy and closure. I was surprised at her response. 

I noticed she'd be online for a long time and won't reply me on time, so I asked her who she was chatting with and she replied someone. I ignored her. This morning she called, while we got talking I asked her about the person she was chatting with. She told me the guys name. And asked if I will forgive her of anything, I said yes. She now said, she was introduced to the guy and they got flirting from the day I came back from my journey and told her I was tired and needed to rest. Her excuse was that, I pushed her to and she just wanted someone to speak/talk to. 

Now, my question is, Should I move on with my business and focus, or, should I continue with the relationship? I don't want to be with someone that gives up on me easily.

P.S I love her so much. And she does too. We've through a lot together.
