am i just paranoid?

I confronted him. he just sed i dont no what to say. then he said wel i guess i should have been more open with you. and then pointed out that the messages were from her not from him.

very long story but ill try and keep it brief!

I had my boyfriends phone the other day, and we both forgot it was in my bag. i have recently got a new phone so have lost all the soppy messages we had been sending each other, so i read thm on his phone. I stumbled across one from another girl, telling him how much she missed him. i then scrolled through the inbox and nothiced there were a lot from her, more thn from me and they were all in conversations as they seemed to follow each other. i read some more at random and discoverd one saying how she likes teaseing him bout her being naked in the shower. I thn read all of them coz i was worried bout the rest. Turns out the ring each other all the time and, text each other more then i text him. A few months ago i discoverd he wudnt open texts from this girl in front of me, and i asked him y. he sed its coz he didnt care, but if they had messages like tht, he wudnt want me to see thm.
now i dont no if im just being paranoid, i feel guilty for reading his mesages, but better for knowing. But i dont know how, or whether i shud confront him in case i loose him.

any suggestions would be good...

i jst tld him wt i put on here. and that im open with him bout who i text, and he said he would tell her to stop if she did it again. aparently she was joking and messing around, but that she must like him. i dont think he had realised.
