Help

at what point, do I (16yo, F) say “this is enough” and walk away? bc I can stay thru a lot. I’d stay until I can’t anymore- then still stay after that point and then wait for them to leave. my ex cheated on me- I told them we could work it out. then they broke up w me.
my bf now (15yo, M), we’re on a “break”? we still say we love each other. he broke up w me, because of my situation. (I’m in foster care and have been since I was 12 I was a runaway when him and I met, and then I had to turn myself in.) saying that it’s hard on him, and he worries too much. but how does breaking up fix that? like if we break up he just magically won’t care anymore?
then he proceeded to say that we can try again when I go live at home and I’m not being bounced around.
he’s bipolar, and keeps saying that, but so am I and I’ve never had my feelings for him waver. I mean bpd is dif in people, but I don’t understand. I want to, but I can’t if he won’t actually talk to me. He needs space, I’m trying to give him that, but I need communication. (he’s getting better at communicating, which I’m very grateful for.) I js want this to work. And I’m trying.
and now we decided to be on a break. and I’m not texting as much. but I always text first. I didn’t know he was alr awake this morning and I texted him gm and then he responded, didn’t even say gm, js I love you?
I can’t ss bc it’s on snap but, here’s how the convo went:

me: good morning I hope you’re sleeping good I hope you have a good day (I might not be able to text until I get back here later td) I love you

him: I love you too
Im at this fuckass beach and im forced to be shirtless 🫩

me:
I’m sorry
I didn’t know you were alr awake mb I’ll stop texting in the mornings

him: don’t

me: ok I won’t
sorry

him: I love you

me: I love you too

him: sent a snap (of the beach)
🫩

me: sorry
gtg js txt if u need me I won’t be able to message u nd don’t plan on it when I get home cuz yea but im here if u need me when I get back if not then k bye

him: Cya. Have a good day

me: k
I love you

him: I love you

I don’t want to bother him but also want to explain how I feel at the same time. I lowk feel like I’m being way too much, and I’m scared. and I’m js 16, so at what point do I leave? I love him, I really do. and I want it to be him. but I’m scared. sometimes he’ll tell me he doesn’t know how he feels, but my love for him has never faltered. Also we’re long distance, so it’s hard- I understand, but he’s worth the wait to me. Honestly.
and I went on Spotify to listen to the playlist he made for me, and there were 2 saves on it. so I looked at his followers and some other girl follows him, and he follows her back. and I’m assuming she’s the one who saved the playlist? Now I’m scared. Im terrified.
I’m not saying I haven’t done things wrong. I 100% have. I’ve started arguments bc I’m insecure and I overthink a lot, and my situation is hard, and I can see where he’s coming from if he really does love me and I can see how it would hurt him- but I’m the one in the situation.
and how could he js leave at one of the lowest points and then literally plan to come back when it’s easier. that’s weird to me. Ik we’re js kids, and maybe I js feel too much. But also as a kid- I don’t want to hurt this much and keep holding on and risk getting hurt even worse. What do I do?
(if anyone needs anymore context lmk, I js need advice.)
