bf playin from jail?

ok so no judgment i dont care for comments abt bf being in jail an shit but yeah he in jail an this girl send me pictures of letters that he sent her and he sends me letters all the time an puts his last name after my first name on letter and he did that for her too and i read some letters and he say he miss her an how he wants a future with her and he tells me every day how much he loves me and wants to be with me bc we soul mates and what were gonna do when we out. i ask him abt this cuz i was like im done w ts im not dealing with this no more i already told you i wont deal with that and he said he only called her and mailed her and hated every video call because he was only playing her so she would send him money. he never wants me to send him $ bc he wants me to save it i mean i have but not like all the time. others send him $ too(fam) anyway. idk what to think yall. like i was so upset when she sent me that. and i wanna ask her more details but idk why i feel like i shouldnt but i think i should know if we been together for 3 years right? like she has a whole family of her own and he sending her apparently "fake" love letters so he can use her $ to call me on the phone.

i ask why he would do this and he said just for the money and i said how can u not feeling bad telli g someone else that we arent together and he said he did he writes abt how shitty he feels and he only did it for the money he dont care about her. idk what to do yall like ts fucking stupid and i want to ask her more about it to get more details to see if he lying if he was with her on the outs but idk would yall ask for more details from her?
