What should I do ugh...

Carissa❤👑👫👭👶👄 • I`m Carissa I have a daughter I’m engaged but also looking for some really close friends and have a little fun every now and then sometimes I’m a sweet down-to-earth person once you get to know me!!!
So there's been some things going on that has been slightly stressful my boyfriend and I but at the end of the day I still want him and he doesn't talk about things much he just me no get stressed he might show a little bit of it but other than that you know not much and I don't know what to do because he kind of let it consume him if we're lucky we might have sex once a week and I guess when it doesn't happen I get a little bit disappointed but it's not a big deal its just sex but he feels terrible what can be done and is there a way I can help
