You posted here and you will hear everything I have to say about your post.
To start if your going to have sex and your partner is promiscious then you need to protect yourself and use condoms. Not being treated for chlamydia is a very poor decision. If your partner will not get tested and treated and you continue to have sex with him then again another very poor decision that can affect your health and possibility of being able to give birth in the future.
Get retested, get your bf tested and both need treatment. Simple as that. Love can make us do many things but to be irresponsible about your health is not smart.
Your neck nodes can be a sign of many things but it is a sign of some kind of throat/mouth infection.
GET TESTED. GET TREATED, SAME FOR PARTNER.
