Should i be worried?

hes acting immature by texting you to say he was talking to some girls, hes insecure, if you just having polite talk then ok as I am friendly and chat to lots of people but next time include him so he won't think is anything going on and show him its just chit chat. Tell him you not into his silly games and talk to him and make him feel secure as something may have happened in his life and hes not confident that you love him enough, so abit of reure and a good talk. Hope hes behaving as usually if someone feeling insecure its cos they are well flirty themselves, hope thats not the case.
