When a relationship feels different, it can be tempting to look for signs that he is about to leave. Less conversation, changed plans or a quieter sex life may worry you, but none of them can establish another person’s intentions. A checklist cannot predict a breakup.
You can take uncertainty seriously without treating every change as evidence of rejection. Focus on the behaviour you can describe, the conversation you want to have and whether the relationship still allows respect, honesty and choice for both people.

Describe what has changed
Replace “He has stopped caring” with something you have observed: “Our last three plans were cancelled without another date,” or “We have not discussed whether we still want to live together.” Specific details give you something to ask about rather than a conclusion you have to prove.
Consider the time period and the wider situation. Work demands, illness, caring responsibilities, money worries or a disagreement may affect someone’s availability. Context may explain a change without making every arrangement acceptable to you.
Name the effect on you too. Perhaps you feel lonely, uncertain about shared plans or tired of organising everything. Your needs matter even when you cannot explain why he is behaving differently.
Avoid treating ordinary differences as proof
Having friends of another gender, spending time alone or declining sex does not establish infidelity or an intention to leave. Sexual interest can change, and affection or commitment never creates an obligation to have sex. Discuss what each person wants without using intimacy as a test.
A quieter argument, different clothing or reduced spending also has more than one possible explanation. Try not to fill in the gaps by checking private messages, tracking location or recruiting friends to monitor him. Uncertainty is a reason to seek clarity, not permission to invade privacy.
Some differences concern compatibility rather than hidden intentions. If you want children and he does not, take both answers seriously. Neither person needs to promise a future they do not want just to keep the relationship going.
Ask for a clear conversation
Choose a time and format in which you can both participate. You could say: “I have noticed we are making fewer plans together, and I feel unsure where we stand. Do you want to continue this relationship?” Ask the question you need answered rather than trying to get reassurance through hints.
Listen to his actual answer. If he wants to continue, ask what that means in everyday terms: making plans, discussing a recurring problem or agreeing on expectations. If he is unsure, you can discuss what space would involve and whether that arrangement works for you.
The NHS guidance on healthy relationships suggests checking your understanding and distinguishing facts from assumptions. You can ask a follow-up question without arguing someone into a different answer.
Consider the response and the pattern
Notice whether difficult questions can be discussed with basic respect. Someone may need time to think, but a request for time should not require you to accept indefinite uncertainty. You can decide when you will revisit the conversation and what you will do if the arrangement continues unchanged.
Look for follow-through rather than relying only on a reassuring statement. A useful agreement is concrete enough to recognise: arranging a time together, sharing a responsibility or returning to an unfinished discussion. No single gesture proves lasting commitment.
Insults, humiliation, threats or pressure are concerns in their own right. You do not need to determine whether they are an attempt to make you leave before taking them seriously. Nor do you have to count good days against harmful ones to justify seeking support.
Choose support and your next step
Your decision can be based on the relationship that is available now. You may want to work on an agreed problem, take time to consider your needs or end a relationship that does not suit you. You do not have to wait for him to make every decision.
If separation is possible, think through practical needs such as housing, money, parenting or support during illness. A serious diagnosis does not determine how a particular partner will behave; ask for the support you need and consider other people or services you can rely on.
If you are afraid of his response or feel controlled, seek private support before relying on a direct conversation or announcing plans. Your safety and independence matter alongside your wish for clarity.
