Reading this chapter actually leaves me feeling hopeful.
I can understand Chris' need for companionship, for a "significant other" (and even his need just for sex on a somewhat regular basis). And I'm glad to see that he has joined a gay support group where, hopefully, he will meet a partner. I'm also glad to see that he is not that needy that he thinks he has to cling on to the first person from the group who had shown an interest in him; that he realises that Will is not what he is really looking for and dumps him. Okay it took him a few weeks to actually end the relationship, but he got there in the end. Hopefully he will continue looking, maybe continue attending the gay social group, and will eventually find the Mr Right. Will is probably a really nice guy, but it seems he just wasn't the one for Chris.
I am a bit concerned about Chris' own self image problems ("I’m nothing appealing; there’s nothing special about me; I’m not handsome or clever or funny.") but I can understand how that may be related to his poor feelings of self worth that likely stem from his upbringing, and his experience with the Church, the ex-gay movement, and his failed suicide and subsequent rejection by his family.
Hopefully, if nothing else, this experience with Will will help Chris realise that he is capable of entering a full time relationship sometime in the future. As Kay told him a few chapters ago: "It's about time you got yourself a proper boyfriend." I'm hoping that the short relationship with Will shows him that, even if Will was not the one for him, that it is possible, and that he doesn't give up completely.
