Be gentle please. 
I have been blessed to make some new friends.
As some of you will know I'm not that good IRL at being assertive if I'm not 100% happy with something, as I don't like to lose friends.
The main one is with a woman who has a lot of problems. I'm genuinely interested so I 'let' her talk at length about these and ask questions etc.
Then I might talk about what I've been thinking/doing for a moment. She will start talking to someone else at the other end of the line during this. It often becomes clear fairly soon that she's taken that moment to talk to her cat! She then will begin to do so with her undivided attention and loudly, rendering my continuing pointless/impossible. I find this a bit annoying as it doesn't seem like she's putting the amount of effort and interest or whatever in that I am. Should I say anything?
Maybe part of it is we need to meet again IRL as there'd be less to distract her/ it's easier to focus on the person. But even so.
The other friend, she has a lot of different problems admittedly.
I'm very rarely down, but for one or two days a couple of weeks ago I wasn't my usual self and said I'd been a bit down. Both of these friends were like this; they said 'oh sorry to hear that.' Whereas I would say 'Aw sorry to hear that- what's the matter/ what's been on your mind?' The person then has the option whether or not they want to discuss it further or not.
Maybe it's just me lol.
Maybe I'm boring but honestly I do make an effort with people and am interested in them and don't find that hard to do. Even if someone was not conventionally interesting I would still be interested.
I listen to them go on about all their stuff and do so happily after all.
