is my girl cheating on me? M32 F28

Hey so. Me and my girl been on and off. Mainly because of boundary violations. Won’t get into it. But I broke with her two weeks ago for hiding her phone. Turned out she was in communication with her ex. Two weeks later she begged for me to take her back I did. So far it’s been good but for the past three days something weird has happened. She very affectionate in person, but texting is very distant. I used to make her laugh in my texts but I can tell the texting is dead or dry but she super into me in person. What’s going on?
