This is very interesting! At a certain age, some girls tend to keep more than one boyfriends not because she's selfish but because they don't want to lose out. Girls and guys are not the same. A girls biological clock is ticking and once the guy she's with is not working at the same pace with the girl, she goes out to look for someone more serious.
And it's normal for her to answer calls here and there. Any attractive girl is expected to be disturbed by different guys.
If the guy feels she not happy with her new relationship, all that is needed is dialogue with her.
Alright Ma'am.
I am glad you came around this week.
