Help! My boyfriend fooled me into drawing a permenent tattoo while his is temporary

Hi Emeh, my boyfriend and I have been dating for 4months. Two months after we dated, he shocked me by saying we should have matching tattoos of eachother's names on our chest.He said this is proof that we are together for life and he loves me so much
I was overjoyed to do it because it wasn't just me doing it and it showed he wanted me forever.
Yesterday, he forgot his phone in my house and I didn't need to but was tempted to look at his messages because he has been acting funny lately. There was nothing incriminating. I decided to go through his pictures to my surprise I found a folder where there were photos of him with over 6 different girls with the same tattoos.
The problem is he had their names on the same spot where he now has my name. I also saw our own photo among them.
I am so scared that while I got a permanent tattoo, he went for a temporary one.
Please what do I do because I am scared of confirming my fears. How do I live my life with a man's name across my boob.
Do I confront him or let it be and hope he did it and had them removed before he met me? Is it also easy to remove tattoos in Nigeria
Please help
